How to clean rust. Home and professional ways to remove rust from metal. How to remove rust from skates

which spoils not only appearance object, but is also capable of bringing it into disrepair over time?

Rust is not a coating at all, which can be easily removed from metal surface a simple cleaner.

Rust is a product of a chemical reaction, in this case the metal interacts with oxygen molecules.

The corrosion process is accompanied by a gradual destruction of the surface and the formation of a rusty, flaky layer on the metal.

Corrosion is especially active at high humidity air, not to mention if metal object is constantly in the water.

Rust is quickly activated under the influence of hydrochloric and acid solutions. Therefore, in order to avoid the need to remove rust from the metal, a good protective layer must be applied to its surface.

But if a corrosive coating nevertheless appears, you can try to remove it with the help of improvised means at home.

At the same time, rust can unexpectedly and reliably settle on the surface of any metal object, on a sink or bathtub, on a car body, on old coins or skates.

At home, you can remove a layer of rust from metal by using mechanical or chemical method impact.

Wherein mechanical way provides grinding of the surface damaged by corrosion.

In this case, it is possible to remove the unpleasant layer, but it is not possible to stop chemical reaction, which is performed in the surface structure of the material.

At the same time, mechanical abrasion can not be used for all products due to the peculiarities of their designs.

For example, on threaded elements, it is better to try to remove rust chemically.

Chemical compositions in the process of removing corrosion enter into interaction with the iron oxides that have appeared, after which they neutralize the oxidation reaction.

Of the existing chemicals, which react with oxides and have high solvent properties, can be called sulfuric and hydrochloric acid.

The acid is not used in its pure form, it is supplemented with special components - inhibitors, which are endowed with the ability to stop the chemical interaction.

If inhibitors are not used, then the acid eats not only a rusty coating, but also damages the base of the metal.

Urotropin is used to control the mutual action of the acid with the metal. Also, miniature galvanized zinc parts are sometimes used as a deterrent.

The destruction of oxides in acid is carried out with the deposition of iron cations on the zinc surface.

In this case, the metal product being cleaned from rust will not be damaged as long as zinc is present in the solution, since, unlike iron, zinc is more active.

In addition to these acids for cleaning rust at home, you can use:

kerosene - removes shallowly ingrained fresh rust;
turpentine - removes old corrosive stains;
lactic acid - with its use, iron hydroxide is converted into an emulsifying salt or iron lactate, the layer can subsequently be removed from the metal with vaseline oil;
zinc chloride - its use allows you to create an acidic environment that helps dissolve corrosion;
kitchen acid and alkali.

Today, the industry produces rust converters and cleaning compounds in a ready-to-use form, they can remove rust before painting, at home.

Their constituent components are different kind acids and galvanic substances.

The converter, which can be used as phosphoric acid, in contrast to the compositions that remove the corrosive layer, converts the damaged layer into a sufficiently strong coating.

How can you remove rust from a car?

If on car rims there are rusted nuts, it is possible to dissolve the formed oxides by carefully smearing them with turpentine.

Or spray with a special anti-corrosion compound, and then leave for a day. After the specified time has elapsed, the connection is unscrewed, the products are dipped in vinegar or calcined over fire.

Rusted arches above the wheels and the bottom of the car are treated with a converter, the surfaces are primed before painting.
If you do not remove rust from the car body, this will accelerate its delamination.

Before treating the rust on the body, the damaged surface is thoroughly washed, cleaned with an emery cloth or subjected to other processing.

Then be sure to degrease and treat with anti-corrosion chemical compounds. A converter is applied, primed with an anti-corrosion agent before painting.

How can I remove rusty areas from the bathroom and toilet?

Metal bath rust can be removed using regular vinegar. With fresh spots, he will cope in a day.

Vinegar is thoroughly moistened with rusty areas and left for 24 hours, then washed off with water and a sponge.
If the rust is on the side walls of the bathroom, then they are moistened with a spray gun as they dry.
You can also clean the bath to its original color using soda, which is diluted with water so that a mass is obtained that resembles sour cream in consistency.

For 20 minutes, the mass is applied over rusty spots, then washed off. clean water and brush off the remaining oxide.

The acrylic surface of the bathroom with a rusty coating is sprinkled with fine salt, then they try to rub it with a cut potato wedge.

For this purpose, you can grate the potatoes, mix it with lemon juice and oxalic acid.

Red stripe coming from drain tank toilet, a common problem. You can remove it with the help of specially designed cleaning products.

The substance is applied to the contaminated area and left for 60 minutes, then wiped with a sponge and washed off with water.

How to remove rust from coins?

Refurbish the look old coins several different methods. Metal products are placed in acetic acid or cleaned with baking soda.

At the same time, it is better to clean silver metal with ammonia or lemon juice.

In this case, lemon juice is more suitable for low-grade metal, and ammonia for high quality silver.

Coins are immersed in liquid and turned over from time to time.

Vinegar is used to remove rust deposits from copper coins.

Coins, for the manufacture of which an alloy of zinc and iron is used, are cleaned with a light composition of hydrochloric acid- products are immersed in a liquid and kept in it until the rust dissolves. Then immediately removed and washed with water.

How to remove the rust layer from the skates?

The appearance of rusty areas on the blades of the skates prevents them from fully sliding on the ice, and if the rust is not removed from the blades in time, one can forget about their purpose.

To remove a rusty coating on skates and make them look new in appearance will allow the use of several actions. To do this, you need to prepare a solution laundry soap, one lemon, baking soda and a couple of soft rags.

First soapy water and with a sponge wash off the dirt from the blades of the skates. Then clean running water rinse metal products, allow to dry completely.

At the next stage, you need to remove the rust, for this, lemon juice is mixed with soda so that a slurry forms.

Then, using a soft cloth, take the prepared mass and rub it on the blades of the skates.

The movement must be performed with light pressure, the procedure itself must last until the corrosion comes off the metal.

In the process of wiping, you can rinse the blades with clean water to assess how efficiently the work is progressing.

Upon completion, the blades are thoroughly rinsed and dried, carefully polished with a soft, dry cloth.

Polishing will remove the roughness from the top layer of metal, which may appear during cleaning.

Also, for full polishing, you can use a specially designed polishing compound.

How to protect metal after rust removal?

In order to adequately protect the metal surface, after the rust has been removed, it is necessary to take care of suitable storage conditions for individual products.

That is, if possible, prevent exposure to moisture.

If there is a technological possibility, it is recommended to additionally impregnate the metal with an anti-corrosion compound, then apply a paint layer.

It is necessary to remove traces of corrosion from any metal in a timely manner, because fresh spots much easier to remove with food.

If you have to work with chemical reagents, then you should take care of your personal protection.

Corrosion on metal objects is the natural effect of steel breaking down due to chemical reactions that occur between its surface and its environment.

You can use vinegar, citric acid, and baking soda to remove rust from metal. In more complex cases, use special means. When selecting, take into account the composition of the material, its durability, as well as the purpose.

Rust removal methods

At home, various means are used to remove corrosion from metal surfaces, tools, accessories on shoes or clothing:

1. Vinegar. It is enough to immerse an object in it for several hours (depending on the degree of corrosion), and the rust will decrease. You can add a few teaspoons of salt to the vinegar for a better effect.
2. Baking soda. Mix baking soda with a little water to form a thick paste. Then it should be applied to a sponge or cloth and used to clean the corrosion.
3. Citric acid. It is applied in the same way as baking soda. If the surface is not heavily rusted, lemon juice can be used instead.
4. "Coca-Cola". Cleaning metal objects with cola is suitable for small items. If the thing is small enough (ring, chains, keys), it is necessary to immerse it completely in a container with a drink and leave it for a while. After removing rust, the product must be washed or wiped damp cloth to remove cola residue from the surface. Also, dry the item with a cloth or paper towel. Otherwise, plaque may reappear.
5. A mixture of vaseline oil (100 g) and lactic acid (50 g). The composition is applied to the surface, after which it is wiped with a cloth dipped in vaseline oil.

Cleaning chrome materials

To remove rust on chrome materials, only water and aluminium foil, which can be used to wipe off chrome-plated material. Procedure:

1. Apply a little liquid to the damaged area.
2. In circular motions, using an aluminum film, corrosion should be removed.
3. At the end of the procedure, wipe the item dry.

Removing stains on clothes

You can quickly get rid of rust stains on clothes and shoes with the help of citric acid or baking soda as follows:

1. The stain should be sprinkled with the selected agent, lightly rubbing with a damp cloth.
2. It is necessary to leave the thing for a while.
3. Wash the item from the powder and wipe it.

One of effective ways– Removing rust stains using lemon juice with a little water. The liquid should be applied to the stain, then sprinkle it with salt and rinse thoroughly after 20-30 minutes.

If you use this method to clean products made of very thin fabrics and materials, you can ruin their appearance.

Effective Ways, allowing you to clean a silver cross at home

How to remove rust from a car body?

To improve the appearance of the machine at home and prevent further corrosion of the coating, you should use the following method:

1. Put on gloves, goggles and a respirator.
2. Close all parts of the car so as not to stain them. Can be used for this purpose protective film by securing it with tape.
3. Wipe and remove varnish around the rust spot. grinder(grinding disc grit - 150) the damaged layer should be removed. First you need to clear small plot around the rusted fragment of the body. Check if the surface is smooth.
4. Gently sand the iron to get to the deepest layers of corrosion. After sanding, it is necessary to apply a rust converter - a product containing phosphoric acid to remove smallest particles. You can buy it at an auto parts store. They are also used to protect metal pipes from corrosion. After using the transducer, you should use a filler that perfectly evens out all possible dents, small pits. Then sand again by hand. sandpaper to get a smooth surface.
5. Apply primer. It works as a base before painting. Then you need to leave the primer to dry for at least 12 hours.

After completing the treatment, you can paint the damaged area, then detach sticky tape. After washing the car, it is necessary to use a product that slows down corrosion. When the machine is dry, you can coat the surface with wax to form a protective layer. It should also be borne in mind that corrosion inhibitors prevent its development, but do not remove rust from the surface.

How to remove rust from tools, bolts and nuts with your own hands

How to remove rust from a tool?
how to clean a coin from rust?
how to remove rust from a knife

There's an answer!

Vinegar

If you've ever cleaned your garage and found a bucket of tools that might have gotten wet and rusty?

DO NOT THROW THEM OUT!

There is a simple solution to restore their appearance for very little money, because buying new tools will cost you a decent amount.

So, did you find bags of nuts, bolts and tools corroded? If you do not know about the properties of vinegar, you will think that they are useless, nothing more. Wear gloves so you don't get rust on your hands, because rust doesn't clean off very well. Gather all your corroded tools, nuts and bolts together. Depending on how many rusty things you found, pick up a container to fit everything. You can use a large basin.

Place your tools in the bucket and fill the bucket with vinegar so that the vinegar covers the contents of the bucket. You will not believe the properties of the almighty vinegar. It will eat rust on tools, bolts and nuts!! It will all bubble up and you will watch the rust start to rise to the top!!!

If your instruments are very corroded, you will need to leave them for a few days, maybe even up to a week. Check them and when you see clean metal then it's time to take them out. Be sure to wear gloves when checking tools! After removing them, rinse under running water and let them dry on a rag, or wipe dry with the same rag. Vinegar cost almost a penny compared to what new tools would cost!

Fresh potatoes contain oxalic acid, which will help us in this matter. If the rust stain is small, such as on a knife blade, then sprinkle the cut potato with salt and clean the knife with it. You can simply hold the potato with salt in a rusty place for about 15 minutes, then rinse and dry.

Vinegar and lemon juice

We mix these two components, which can be found in any kitchen in equal proportions, and apply the mixture to a rust stain on metal, clothes or tiles. For metal, the mixture must be kept for two hours, for other materials, 15-20 minutes. After finishing the treatment, we also wash and dry the surface.

Baking soda

To prepare the composition, mix ordinary baking soda with water, so that a not very thick slurry is obtained. This mixture is applied to the rusty place of the metal surface for 15-20 minutes, after which we remove it with a metal washcloth. You may have to repeat this process a couple of times.

Coca Cola or other soda

Enough modern facility to remove rust. For the first time, American housewives began to use Coca-Cola, who noticed that it coped well with rusty spots. It's all about phosphoric acid, which dissolves rust. So think again about whether it is worth drinking water that dissolves iron oxide.

Alka-Seltzer

Another miracle of modern chemistry that helps the suffering. It will help us remove rust spots from aluminum utensils. Place the dishes in a container, fill with water and add 4-6 tablets of alka-seltzer. After 5-10 minutes, rinse with clean water and dry.

Ketchup

Yes, and he will fit in this case. Apply ketchup or tomato sauce to the rust stain, wait 5-10 minutes, then wipe dry

CILIT toilet bowl cleaner

We take an old rusty scraper:

And we immerse it for several hours in CILIT toilet bowl cleaner. Is there a difference before and after?

As for professional methods,

then there are a large number of converters or rust removers on sale that act on the same principle- the composition enters into a chemical reaction with rust, converting it into a dense black or dark blue coating, which can then be painted. As they say, quickly and reliably. I recommend using these tools to remove rust on water pipes Oh, metal bars structures and other all-metal objects. It does not make sense to bring specific funds, since it is not worth advertising for any brand, since its products may not suit everyone. Converters and rust removers are sold in auto shops and auto departments of building supermarkets. So that you do not have to use all these rust removers, first of all take care of its prevention - regularly paint metal surfaces, treat them with anti-corrosion impregnation and protect them from moisture.

Working with Audyushka Sooo dragged on … Now I've been struggling with rust for days. I fight by means of metal brushes for a drill and petal circles for a grinder. Flap wheels and steel brushes are good at removing rust, but they are very rough on living metal. Brass brushes are more friendly to metal, but they also remove rust more weakly.

There is, of course, also sandblasting - it removes rust with a bang (and it cleans rust well from shells), and it is quite soft to metal (more precisely, to steel). But its in open form I don't use it in the garage (maximum in the sandblasting chamber), and the weather does not allow it outside.

In search of a way to accurately and efficiently remove rust, I came across the B-52 Rust Remover.

In the internet, darkness is dark descriptions of his theoretical work, but I almost did not come across a practical test. So I decided to test on a rusty piece of metal from my typewriter.

According to the instructions, the product must be applied to the surface with a layer of 1-2 mm, left for 15 minutes, then rinsed with water, wipe the surface with a dry cloth, and then wipe with the 646th solvent; if necessary, the procedure can be repeated.
Here is my "lab mouse" — clipping from the rear left fender (above the lantern).

Immediately inflicted the destroyer locally. Circumstances so developed that I did not endure 15 minutes, but 30.

Wipe off with a wet cloth.

The result, though not phenomenal, but it is! Apply the remover to the entire surface.

Periodically rubbed with a toothbrush.

About 30 minutes after application, I wiped the "mouse" with a wet, and then with a dry rag.

Half an hour later I got this result.

The experiment could be continued, but I decided that it was enough to translate the tool, because its effectiveness is now known.

As for the 646th solvent, I will say that it is necessary in the work. They definitely need to wipe the surface at the end of each cycle (after wiping dry), otherwise the steel starts to turn red right before our eyes!

Finally, a video of the process of destroying rust with Pepsi-Cola, which acts the same way as Coca-Cola. Actually, any soda containing phosphoric acid will do.

Rust will form on metal if it is not coated with an anti-corrosion agent. She undermines the metal, destroys it. The unpleasant appearance of a rusty metal object causes a desire to get rid of red spots, restore its luster and beauty. To remove rust from metal at home, you need to make a lot of effort.

There are many remedies for rust on metal. We will introduce you to some of them. Today we will tell you how to remove rust from metal.

How to clean rust from metal

How to get rid of rust on metal using chemicals?

To prevent rust from reappearing, treat the metal with an anti-corrosion agent.

You can remove the corrosion of the metal by applying hydrochloric or sulfuric acid to it. Be sure to use an inhibitor, adding it to aggressive substances, thereby weakening the effect of the acid on the metal, preventing its destruction under the influence of the strongest agent.

Dip a brush in it and brush it onto large metal parts. Small parts soak in a 5% solution of sulfuric or hydrochloric acid with the addition of urotropine as an inhibitor (0.5 g per liter)

Potato peels can also serve as an inhibitor, softening the action of acids. AT three-liter jar put them up to half of the vessel.

Stir the mixture constantly for 20 minutes. Then pour the water into a previously prepared container and cover the rusty place on a metal object with this product.

In place of the corrosive surface, plasma flashes are formed, which contribute to the evaporation of rust.

Folk remedies for getting rid of rusty plaque on metal surfaces

If the rust is not completely removed, leaving small spots on the mixer, repeat the procedure again.

Sprinkle everything with salt rusty places on metal and drizzle with lime juice or lemon juice, leave for a few hours. With a thick lime peel, rub the remaining rust on metal products.

How to remove stubborn rust from metal at home?

100 g of vaseline oil or paraffin and 50 g of lactic acid are mixed, applied to rusted metal and rubbed on its surface, then wiped with a dry cloth. The salt formed when exposed to lactic acid dissolves in paraffin, so there will be no rust on the metal.

Another effective remedy will help you get rid of rust on a metal object: dissolve 5 g of zinc chloride and 0.5 g of cream of tartar in 125 g of water.

Rust dissolves with acid.

You can unscrew a stuck, rusted nut in this way: make a plasticine cup around the nut, put a piece of zinc in it and fill it with sulfuric acid.

It will dissolve the rust on the nut. Its remains will settle on a zinc particle. The next day, loosen the nut quickly and easily.

Another rusted nut can be unscrewed by moistening it for a while with turpentine or kerosene.
The kerosene will eat away the rust spots and the nut will come loose. If the nut has grown into the bolt, then a soldering iron will help.

From high temperature the rust will break down and the nut will come off the bolt. Wipe it again with turpentine or kerosene and you will quickly turn the nut.

Today we shared our knowledge and experience on how to remove rust from metal. Use the best methods in your opinion, and the metal surfaces will return to their original appearance.

Rust appears on metal products due to moisture or mechanical damage, when air penetrates inside the iron sheet due to a scratch or crack. It starts chemical reactions, the material oxidizes, and destruction begins. Corrosion can be stopped with synthetic and folk remedies. Which option to choose? Depends on the area and degree of damage.

natural remedies

It is enough to clean small red spots with a stiff brush or sandpaper, and then cover the metal product with paint. She will protect from reappearance corrosion. If the brush does not work, natural remedies will help.

Potato and lemon
Dishes and small parts covered with a thin red film are wiped raw potatoes cut in half. The vegetable contains an acid that dissolves rust. In small quantities, it does not harm the metal. The treated area is left for 5 minutes, and then wiped with a soft, lint-free cloth, removing the remnants of juice and plaque.

Rusted products are also cleaned with potato gruel, to which ground lemon and 1-2 tablespoons of coarse salt are added. The mass is applied to the damaged areas, left for 15 minutes, then rubbed with a toothbrush and washed off with a damp cloth.

Dry lemon zest is used instead of sandpaper. It is useful if rust has appeared on a metal jewelry or other fragile item. The peel works softly and delicately, leaving no scratches on the surface.

Zest can be replaced with a gruel of lemon juice and fine-grained salt. The components are mixed and applied with a toothbrush. Wait 15 minutes for the acid to dissolve the brown film.

Stubborn rust is removed with a solution of lemon juice and table vinegar. Liquids are mixed in equal amounts, applied to the damaged object with a sponge or cloth. It is advisable to put on hands rubber gloves. Leave on for 2-3 hours, rinse warm water and rub the area with a hard metal sponge.

Soda and flour
How to clean old rusty coins so as not to damage them? baking soda. Dilute 2-3 tablespoons of the powder with warm water until a thick homogeneous consistency. Put the coins in a gruel of soda, remove after 20 minutes. Scrape off the red plaque with a wire brush or washcloth. Repeat the procedure if once was not enough.

Items made of brass are recommended to be cleaned with table vinegar. Dissolve 10 g of table salt in 120 ml of liquid. Add wheat or corn flour, you can use oatmeal powder. Knead a thick dough, like on pancakes, and apply to damaged areas. After 30 minutes, wipe off the paste with a soft cloth, rinse the brass item in warm water and dry with a towel.

Important: Do not prepare a solution of wine or apple cider vinegar. Only table transparent will do. Other varieties leave stains on the metal surface that are difficult to erase.

Citric and oxalic acid
Rust is softened with lime juice, which is mixed with salt. But it's cheaper to use citric acid. Dissolve 3 sachets of the product in a liter of water. Boil the liquid and put rusty nuts, screwdrivers, knives, jewelry or other items into it. Bubbles on the surface of the water indicate that a chemical reaction has begun.

Leave metal products in a solution of citric acid for 8-12 hours. Softened plaque is removed with a toothbrush or washcloth.

Rust is removed with oxalic acid. The tool copes even with serious damage, but emits toxic fumes. Work with the substance only in ventilated areas. Be sure to use protective suits, respirators, special goggles and rubber gloves.

For a glass of water you need 4 tbsp. l. oxalic acid. The solution is thoroughly stirred, and then rusty tools are immersed in it. Dishes and jewelry that come into contact with the skin should not be cleaned in this way.

After 30–40 minutes, the object is removed using tweezers and the red plaque is removed with a toothbrush. metal product washed several times in large numbers warm water, and then dry with a towel or soft cloth.

Unusual solutions

Not only potatoes and lemon juice remove rust. Sodas, hangover pills, and even ketchup help. If the natural compounds did not cope with the red bloom, the damaged product will be saved by chemistry.

Cola
The composition of sweet soda includes phosphoric acid, which removes corrosion. Cola is poured into a plastic or glass container, rusty products are immersed in the drink. Remove after 5-8 hours, rub with a toothbrush. Soda is sprayed onto pipes or a machine from a spray bottle or applied with a sponge. Wait until the rust is soft, and brush off the plaque with a brush or crumpled baking foil.

Metal objects are soaked not only in Coca-Cola. Cheap sodas have similar properties. The main thing is that they contain phosphoric acid.

rusty tomatoes
Is there an expired package of old ketchup in the fridge? Or bank tomato juice? The product is not thrown away, but used to clean tools or knives from rust.

Treat stains with ketchup or juice, leave for 20 minutes. Remove the remains of the tomato product with a rag along with plaque, rinse the metal surface with warm water.

No hangover, no rust
Bring back the shine aluminum cookware maybe Alka-seltzer. Dissolve 5 tablets in a jar of water, immerse spoons or mugs in the liquid. Remove after 15 minutes, brush with a toothbrush and rinse under the tap.

tooth powder and fish fat
Metal rivets on clothes, accessories and tools are cleaned with a mixture of crushed white chalk, tooth powder and liquid glycerin. Dry ingredients are mixed into equal parts. The liquid ingredient is added to make a paste similar to thick sour cream.

The agent is applied to rusty areas and left for a day. Remove the remnants of the mass and plaque with a toothbrush, be sure to rinse the metal object under the tap and wipe thoroughly with a soft cloth.

Iron water pipes, fittings and car parts are recommended to be cleaned of rust with fish oil. The product is applied in a thick layer on the entire object, left for 3-5 hours. Rust becomes soft and pliable. It is easy to remove with a toothbrush or sponge.

This method has a plus: fish oil creates a protective film that prevents corrosion and increases the life of pipes or tools.

Chemical experiments

Lactic acid or zinc chloride can remove rust from plumbing pipes, tools, fixtures, and metal poles. The substance enters into a chemical reaction with a red coating, and it changes color, becomes dark blue or black. Rust is removed with a cloth dipped in a greasy cream or oil. Some types of metal darken after such cleaning, so it is not recommended to clean dishes with zinc chloride or acid, because the pipes can be painted, and the plate or spoon will have to be thrown away.

Option 1
It will take 100 g of vaseline oil, to which 50 g of lactic acid is added. Stir the components until smooth, apply to rust. Red plaque under the influence of acid will turn into salt, which is easily cleaned with a toothbrush or sandpaper. After treatment, the metal surface is wiped with a soft cloth soaked in petroleum jelly or unrefined sunflower oil.

Option 2
A solution is prepared from a liter of water, 50 g of zinc chloride and 5 g of potassium hydrotartrate. Tools are immersed in liquid, left for several hours or days, depending on the degree of damage. Then they are removed, cleaned with a stiff brush and rinsed with water.

Work with chemicals carefully, wearing rubber gloves and other protective equipment. Remove instruments from the solution with tweezers, do not put your hands into the liquid.

100% result

Stop corrosion agent, consisting of two solutions. The first one includes:

ammonium - 53.5 g;
formalin (40%) - 200 g;
caustic soda - 52 g.

Dissolve the components in 500 ml of filtered water. While the first solution is infused, prepare the second. It will take 1 liter of water and 100 ml of sulfuric or hydrochloric acid. Stir the components, pour 30 ml of the first into the second solution.

Before acid treatment, wipe the part with gasoline to degrease. Immerse the rusty object in the solution for 10 minutes, remove with tongs and rinse with water. It is not necessary to rub with a brush, the plaque will completely dissolve and independently lag behind the metal surface.

Electrochemical method
Tie a piece of zinc to a tool or spare part. Put in water, add sulfuric acid: for 1 liter of liquid 20–30 ml of the substance. After a few days, the plaque will dissolve, the part will become clean and shiny.

To quickly remove rust, it is recommended to prepare a concentrated preparation from water and tin chloride and immerse a metal object in it. Hold for 3-5 minutes, rinse under running warm water. Wipe dry with a clean towel.

Perfect shine
In machine oil, put a few tablespoons of crushed charcoal. Moisten a rag in gruel and clean the part covered with a red bloom. The tool removes rust and polishes the metal surface.

Special funds

Shops sell solvents and converters designed to fight corrosion. How are the drugs different?

Solvents enter into a chemical reaction with plaque, changing its structure. Gel-treated rust can be removed from the surface of the part, usually with a dry cloth, without effort. The most popular and inexpensive drug "Rust Neutralizer VSN-1".

The main component of such a tool is oxalic or phosphoric acid.

Converters, which are produced in the form of suspensions and emulsions, as well as solutions, not only remove rust, but also form a protective film on the metal surface. It stops corrosion and prevents its reappearance.

The active component of the converters is tannin or phosphoric acid.

Features of use
Details before processing are cleaned with a stiff brush, removing loose particles of rust and dust. Then the surface covered with a red coating is disinfected with gasoline or white spirit. The drug is stirred and applied with a brush, evenly distributing over damaged areas. If it turns purple-blue, a reaction has begun.

Brown plaque is removed with a mixture of 15 ml of tartaric acid, 5 ml of butanol and 30 ml of phosphoric acid. Dilute with a liter of water, process metal parts.

Rust removers must be handled with care. Most of them contain toxic substances or aggressive components that can burn the skin or mucous membranes. After plaque removal, it is recommended to carry out preventive treatment parts with gasoline or kerosene, because it is easier to prevent corrosion than to stop this chemical process.
