Rust stains are the most persistent and not easy to remove. Those who had to do this know that removing rust without special tools is a very difficult task, and the method of cleaning the material depends on the age of corrosion.
Today, many different products are produced to get rid of plaque, but they should be used carefully, because most of them are aggressive and contain detergent components, abrasive substances and acids. Moreover, for different surfaces there are methods and means of removing rust spots.
Rust removal from metal
Work to remove corrosion from metal surfaces must begin immediately upon detection of its smallest manifestations. Initially, the removal is carried out using a steel brush or sandpaper. You can try a special solution such as a rust converter. To do this, the loose layers should be removed, the surface treated with solvent or gasoline for degreasing, and then apply the converter to the metal. The surface color will gradually turn bluish or purple. When working with such solutions, you must observe safety precautions, use protective equipment, and if acid gets on your skin, immediately rinse it with water.
Rust removal can be performed by electrochemical method. To do this, a piece of zinc is attached to the metal, after which everything is immersed in water acidified with sulfuric acid. After a few hours, the rust should go away. After that, the product should be washed and dried.
It is possible to quickly get rid of corrosion with the help of a solution of chlorine tin, which treats the defective surface for several minutes and then rinses with warm water and dried. Rust is also removed with phosphoric acid, which is used as a converter.
To clean the metal from red plaque, fish oil is sometimes used. The product is applied for two hours in a thick layer, after which the rust leaves. In addition, fish oil forms a protective film that prevents further oxidation.
Removing rust from clothing
It is very difficult to remove stains from clothes, because the oxides are eaten into the fibers and are not easy to remove. To restore the original appearance of the fabric, you can use lemon juice. For this, a slice of lemon is wrapped in gauze, applied to the iron and then ironed. Light tissue can be treated with hydrogen peroxide.
Rust is also removed with vinegar. To do this, in a glass of water, two spoons of heated vinegar are bred. The plaque is dipped in this solution and incubated for several minutes, after which it is rinsed with diluted ammonia. Colored fabrics are cleaned of rust with a mixture of white chalk and glycerin, which are taken in equal parts. The gruel must be applied to the stain and then left for a day, after the thing is rinsed and washed.
Removing rust from plumbing
To prevent rust stains from appearing on the toilet, bathtub or wash basin, care should be taken to keep as little water as possible on the surfaces. At the slightest manifestations of rust, products should be cleaned, otherwise the oxides will penetrate the enamel and begin to corrode it. Rust removal is carried out using heated vinegar along with sodium chloride, fat, hydrogen peroxide and ammonia (1 to 10), cleaned with a solution of soda.
Abrasives (powders, salt, soda) on enameled surfaces are applied only with soft sponges, and for acrylic they can not be used at all. For clarification, it is recommended to take liquid formulations - vinegar, lemon juice or soap. However, rust, which is heavily ingrained in a sink or bath, is almost impossible to clean, it is easier to simply paint over.
