Method # 1.Mechanical

The very name of this method implies mechanical impact on the product using abrasive materials and a manual or mechanized tool. To get rid of rust on metal, you need to use special metal brushes, emery cloth or abrasive wheels. This method is useful to remove corrosion from surfaces that have large areas and more uniform shapes.

First of all, these above surfaces must be cleaned of foreign debris and, only then, with a metal brush or abrasive wheel worn on a drill, remove rust until a clean surface appears.

Important! Use for this purpose can and grinder.

If the contaminated surface has a complex shape or rust has appeared in hard-to-reach places, you can manually remove rust.

Important! Use abrasive sandpaper or metal brushes for this purpose.

The mechanical method is only applicable to products with a sufficient thickness of metal. Make sure that the place does not become thinner than other parts of the product during processing.

Important! Using a mechanical method of cleaning, pay special attention to the protection of hands, eyes, open parts of the body. Strictly observe the safety rules when working with an electric tool.

Method # 2.Chemical

This method consists in the use of a chemical agent against rust. It should be used to clean small parts with a complex shape.

Important! Note that the process of removing traces of corrosion you can spend from several minutes to several hours. It all depends on what composition you will use.

Safety instructions

As a rule, chemical compounds are corrosive liquids that react with metal and iron oxide( rust), so adhere to these rules:

  1. Using chemical rust solvents, work in a well-ventilated, ventilated space, as in the cleaning processdifferent harmful vapors may be released, including pairs of acids.
  2. Handle chemical products very carefully, as they can cause chemical burns if they get on the skin or mucous surfaces of a person's body. Work only in special protective clothing.
  3. Strictly follow the instructions to the selected tool against rust, as the method of application can be different.

Important! In case of contact with the skin, rinse immediately with plenty of water and contact a hospital.

Kinds of solutions

To get rid of rust at home, you can use different types of chemicals.

Chemical solvent

Is the most popular and modern means of fighting rust. In its composition, phosphoric or concentrated oxalic acid, which contribute to the complete removal of the oxide from the metal.

Similar to rust against aerosol paint, it can also be used as a primer for a paint layer. Use the solvent as follows:

  1. With a hard brush, first remove the peeling rust.
  2. Apply evenly to the rusted area the solvent.
  3. After 30 minutes, wipe the area with a cloth.
  4. After removing corrosion, treat the metal with a deterrent.

rust converter Today, this rust remover is very popular. It can stop the corrosion process. In other words, this means converts rust into a protective film by the principle of preservation.

The rust converter stops its development and causes a completely different function: rust changes its composition into chemically pure iron.

Important! The minus of using this tool is a change in the color of the surface of the metal( it becomes blue-violet).

Converters are available in the form of a spray, solution and suspension. Before you can get rid of rust through such a chemical, you need to clean the metal from the peeled rust.

Important! Remember that after using the rust converter, the surface must be painted.

Method # 3.Electrochemical

To use the electrochemical method requires a direct current source and a special solution - electrolyte. The scheme of your actions to get rid of rust in this way will be as follows:

  1. Clean the part to be placed in the electrolyte.
  2. Connect the negative contact of the current source directly to the part so that it does not come into contact with the electrolyte.
  3. Connect the positive contact to the electrolyte.

Important! When the voltage is connected, an electrochemical reaction will begin that will separate the iron oxide from the part. Rust will settle on the bottom of the solution. The cleaning process is much faster due to electricity. It can be used both for small parts of complex shape, and for large parts, it all depends on the presence of electrolyte and packaging.

Method # 4.Folk remedies against rust

The use of folk remedies refers more to the chemical method. However, these funds can clean small contaminants without the use of special reagents and electrolytes, and are also less dangerous.

Important! The effectiveness of these tools against rust is not so high, but to clean the plaque of corrosion small parts with the help of these tools is possible.

Many products available in every home can become reliable assistants in the fight against iron oxide. Let's consider some of them.

Lemon or citric acid

To get rid of rust, buy a small package of citric acid in any supermarket and use it this way:
