Read about how to remove rust from a car body in different ways in the article.

How to deal with corrosion?

You can get rid of rust on the car body using folk remedies or specialized formulations. In some cases, they resort to mechanical cleaning and even electrochemical metal treatment.

Elimination with folk remedies

Folk remedies have certain advantages:

• they are cheap;
• safe for metal and human health;
• do not have a pungent odor;
• easy to use;
• have high efficiency.

To get the result, you need to follow the instructions for use for each specific product. He will tell you about removing rust with folk remedies this article.

Vinegar

The acid dissolves rust. To clean the body from corrosion, use table vinegar or essence.

Mode of application:

1. Rub the damaged area with aluminum foil to remove any loose metal.
2. Dampen a sponge or cloth with acid.
3. Apply the cloth to the rusty place, leave it for an hour in the form of a compress.
4. Remove material.
5. Rinse the body with clean water and allow to dry.

The thicker the rust layer, the higher the concentration of vinegar should be. More about the method - here.

How to remove with phosphoric acid?

To get rid of rust, a solution of phosphoric acid is used. Its optimal concentration is 15-30%. If the product was purchased in powder, then it is diluted with 10 parts of water.

Removal instructions rust:

• the solution is applied to the metal with a brush made of natural wax;
• if the plaque is thick, it is first cleaned with sandpaper;
• the acid is left on the metal surface for 2 hours - at this time, care must be taken that it does not dry out;
• complete the procedure by washing.

For greater efficiency, the rust inhibitor catapin can be added to orthophosphoric acid: 2 g per 1 liter of solution. More about the method - here.

Soda

You can get rid of corrosion with baking soda. Mode of application:

1. Prepare soda gruel by diluting it with a little water.
2. Apply the product to the metal surface and leave to dry completely.
3. Wash off the baking soda with clean water.

Sparkling water

Coca-Cola or Pepsi can handle rust just as well as purchased products. This is possible due to the presence of phosphoric acid in their composition.

Mode of application:

• abundantly soak the fabric with a carbonated drink;
• attach it to the damaged area;
• cover with polyethylene on top, leave for 12 hours;
• remove the compress along with rust, rinse the area with clean water.

To deal with corrosion, you need the original Coca-cola, not its cheap counterpart. More about the method - here.

How to treat with citric acid?

Citric acid works in a similar way to vinegar... To prepare the solution, you will need 40 g of acid and 3 liters of water.

The resulting composition is applied to the cleaned areas and kept for at least an hour. All that remains is to rinse off the product with clean water and dry the metal surface.

If the corrosion is extensive and deep, then the amount of acid is doubled.... More about the method - here.

Removal with special compounds

You can get rid of rust on the body with the help of special products that are sold in stores for car enthusiasts, as well as in online stores.

How to fix converters?

On sale you can find funds from different manufacturers. However, all work converters according to a single principle: they do not just dissolve rust, but convert metal oxides into a protective layer. This allows not only to remove plaque, but to protect the body from further destruction.

Converters can be of 3 types:

1. Primers-modifiers. With their help, they stop corrosion and level the surface of the body for subsequent painting.
2. Converters of iron oxides into poorly soluble salts.
3. Rust product stabilizers. They convert unstable oxides into stable compounds.

Regardless of the composition chosen, the instructions for their use do not differ significantly. Procedure:

• clean off the top layer of rust from the body;
• apply a converter to the affected area;
• leave to dry completely - average duration - 30 minutes;
• remove the film that appears on the metal surface with a metal brush;
• rinse the surface with clean water, apply paint or other protective compound.

Not all converters need to be washed off; some formulations are left on the metal as they are. Therefore, it is important to read the instructions before use.

Galvanizing kits

A set for galvanizing a body (Zinkor) is a kit that is used to remove rust, followed by galvanizing metal.

It includes:

1. A solution for removing rust and degreasing surfaces.
2. Solution for applying a protective layer.
3. Stainless steel electrode.
4. Zinc tip electrode.
5. The wire.

One set is enough to process 1 sq. m. The cost of Zinkor is about 1000 rubles.

How to get rid of with auto-plasticine?

Autoplasticine is a unique plastic material, which allows you to get rid of corrosion and prevent its further spread.

The composition includes a rust converter, due to which the desired effect is achieved.

To enjoy autoplasticine just... It is applied to the damaged area of ​​the body, thereby isolating it from environmental factors.

However, when buying, you need to pay attention to the fact that the packaging is marked "for the body", since there are compounds on sale that are used only for the bottom. The average price of auto-plasticine is 100 rubles.

Use the composition as a temporary measure. Autoplasticine can stop the spread of corrosion, but it will not be possible to decorate the damaged area with its help.

Primer-enamel or paint

Rust paint designed not only to mask the affected area, but also to prevent further spread of corrosion... This is possible thanks to the included converter.

It is enough to lightly rub the body surface with a brush to remove loose rust. Read about car paint rust here.

How to electrochemically etch rusty deposits?

The essence of the electrochemical method is simple, it boils down to the transition of atoms from one metal to another. To implement the method, you will need:

• a constant current source, such as a car battery;
• electrolyte (3 liters of water and 1 tsp. soda ash);
• metals with different electrochemical activity.

The procedure is as follows:

1. The part in need of cleaning is removed.
2. Rust is removed with a scraper or brush.
3. A steel plate is lowered into the electrolyte by connecting it to the "+" of the battery.
4. The part that needs the scraper is connected to the "-", after which it is also dipped into the solution.
5. Power on. The start of a chemical reaction will be indicated by air bubbles and a bubbling solution. After a while, it will turn black.

Full cleaning takes about 5-6 hours. Then the part is removed from the solution, washed and dried. More about the method - here.

Mechanical method: how to clean the surface?

The mechanical method of removing rust is the simplest, most affordable, fast and effective method. However, it has two significant drawbacks.

Tools you can use to remove rust:

• corset;
• brush with metal bristles;
• sandpaper;
• sanding machine;
• aluminium foil.

For the best effect, the body part is pretreated with a rust converter. Only after this is it recommended to start the main procedure.

When working with tools, you need to control the pressureso as not to damage the metal not affected by rust. After completing the cleaning, the body is primed and painted.

Prevention

To prevent the appearance of rust on the body, adhere to the following recommendations:

1. The car should be washed regularly, both in winter and summer. This will remove aggressive components that are sprinkled on the roads, as well as get rid of dust and dirt, under which the metal quickly collapses.
2. An anti-gravel film is applied to the hood and roof.
3. Mud flaps and wheel arches must be installed on each wheel.
4. Anti-corrosion treatment of the body must be carried out once every 5 years.

The body should be inspected regularly for rust. When the first signs of corrosion appear, emergency measures are taken.

Helpful information

For a successful body rust removal process, you need to adhere to the following recommendations:

1. All work must be carried out in accordance with safety measures. Hands are protected with gloves, and eyes with special glasses.
2. When treating the body with caustic substances, you need to take care of high-quality ventilation in the room.
3. It is impossible to keep acid on the surface of the body for too long; it can destroy intact metal.

Conclusion

There are many ways to get rid of rust on the body. For this purpose, improvised means and specialized formulations are used. They also resort to mechanical and electrochemical cleaning methods. Sometimes a combination of several methods is required to obtain optimal results.
