Corrosion of a metal is a natural process that occurs as a result of exposure to environmental elements such as oxygen and water on a metal surface. Destroyed by rust, the metal loses its strength and durability and looks simply unaesthetic. But did you know that a metal surface can be completely cleaned of an ugly red coating, moreover, corrosion can be stopped and even the process reversed.

There are two ways to remove rust: chemical and mechanical. With the mechanical method, you need sandpaper, or a metal brush, it all depends on the specific case. Of course, it should be remembered that any abrasive material will leave scratches and grooves on the metal surface, so the mechanical method is not always advisable. In addition, in large areas, machining takes a considerable amount of time. The procedure can be accelerated by using a power tool: a drill with a special nozzle or a grinding machine.

The chemical method involves surface treatment with special agents that effectively remove traces of corrosion. A substance called “rust cleaner” is available for sale. Release form - liquid, paste or gel. Before applying the product to the surface, use a brush to remove loose layers of rust. Then, if the item is small, it may be completely immersed in the solution, otherwise it will require the application of liquid or paste on the treated metal surface. In any case, read the instructions that came with the composition

Another method of combating corrosion is rust conversion. As a result, iron oxides are converted to stable phosphates. All commercially available rust converters are based on phosphoric acid. After applying such funds to a rusty metal surface, a chemical reaction occurs, after which the treated areas will change their color to bluish-purple. At the end of the process, the areas on which the product was applied should be washed with water, be sure to thoroughly wipe and soil. Sometimes, before applying the primer, washing with water is not required, read the instructions applicable to your composition.
Useful advice
A few additional recommendations. There are also “folk” remedies for the fight against corrosion. If the size permits, the rust-affected metal can be placed in a solution of vinegar, after dissolving the rust, the object must be washed and wiped dry. An interesting method of surface treatment with fish oil. This method will not only cope with brown plaque, but also penetrating deep into the rust creates a kind of film on the metal surface, which prevents further destruction of the metal.
