Everyone knows that iron surfaces, under certain conditions, tend to oxidize over time, even if they have a protective coating on them. If the time is not taken, then removing the rust from the metal can be very difficult. The oxidation process not only spoils the appearance, but also gradually makes the product unfit for further use. If the objects used in everyday life tend to become covered with rust, then to get rid of it, one can use one of the ways to remove the formed plaque in the home to maintain the metal surfaces in good condition.

There are both factory tools, and folk methods that allow you to get rid of rust on iron objects. Of course, any landlord will try to wipe off the plaque with improvised materials so as not to spend money on buying cleaning compounds in household chemical shops. Some surfaces can be cleaned with a metal brush, sandpaper or other tools that use the principle of abrasive action on the material being processed. But the removal of rusty plaque by this method makes sense only if, after such cleaning, the product does not lose its performance or aesthetic appearance. For example, this procedure should not be done with galvanized or enameled items.

Several ways to clean rust with

tools There are many more gentle folk methods, the most famous of which are listed in the following list.

  1. Influence for 2 hours on the oxidized object with a mixture of vinegar and lemon juice, prepared in a 1: 1 ratio.
  2. Application on a rusted surface of tomato sauce or ketchup for 10 minutes.
  3. Treatment of the product with baking soda diluted to pasty consistency, and subsequent removal of the applied layer in half an hour.
  4. Immersion of a rusted thing for several hours in Coca-Cola or wetting it with a surface that has been corroded.

The listed methods are especially popular, since it is possible to remove rust from metal with their help without visiting the household chemical shops before, because with the search for a cleaning agent there are usually no problems. If you can not get rid of the rust completely, then the procedure can always be repeated or used for cleaning in more efficient ways.

A good result can be achieved if you try to remove a rusty coating from metal surfaces, using another method available for exercise at home. It is necessary to pour a little salt on the problem site and topple it with lemon juice, then cut the potatoes in half and rub it with a rusty stain. The acids contained in lemon and potato juice will do their job, and the salt in this case acts as a soft abrasive. After a while, to remove reaction products and residual cleaning substances from the surface being treated, it should be washed with a wet sponge, and then wiped dry( which, by the way, should be done with any other method).

Lactic acid also interacts well with oxidized iron. But that the formed salt of this acid can be easily removed from the surface, lactic acid before use is mixed with vaseline oil in a proportion of 2: 1.This substance has the property of easily dissolving iron lactate. After that, after a while, the treated object is enough to wipe with a dry cloth to restore its original appearance.

Tip

To keep metal surfaces in good condition after removing contaminants, they must be wiped dry and then wiped with alcohol or acetone. Some objects are wiped with a piece of cloth impregnated with engine oil or kerosene, and others - covered with a layer of wax for storage.

Some pharmaceutical products are able to eliminate rust

Rust remover removal with chemical reagents and factory cleaners

Getting rid of rust by household means is not so easy, especially if its layer is already thick enough. Therefore, if you are friends with such a science as chemistry, then for you there are still some options for solving this problem. One of them is Alka-Seltzer, sold in the form of tablets. Having dissolved 5 tablets of this substance in water and having immersed in it a processed object, it is possible to receive excellent result in some minutes. Another chemical agent for cleaning corroded surfaces is a mixture dissolved in 100 ml of water, which contains 0.5 g of potassium hydrotartrate and 5 g of zinc chloride.

The most effective way to get rid of a rusty plaque chemically is by exposing it to a solution of sulfuric or hydrochloric acid of low concentration. But these substances are so aggressive that they can also interact with non-oxidized metal, damaging the surface structure. Therefore, to prevent such negative consequences, acid inhibitors are admixed with inhibitors, which can serve as the following substances that prevent dissolution of the metal:

  • urotropine, added in an amount of 0.5 g per 1 liter of a 5% solution;
  • potato tops, stirred in acid for 20 minutes;
  • zinc, which takes on an acid "blow", because it is more active metal than iron.


But how to clean the knife of rust( or other household items), if you are not friends with chemistry, and the people's means do not help? In this case, it is always possible to visit one of the specialized stores where you can purchase a suitable product, for example a rust converter. The principle of action of this composition is that, interacting with the oxidized metal, it forms on the surface of the product a thin iron film of a chemically pure substance. As a result, the oxidation process stops due to the blocking of oxygen access. Such a factory tool can be sold in the form of a solution, an aerosol or a suspension. After processing the metal, its surface acquires a bluish-violet hue.

Learning the methods described above will help you decide which one to use to rust. But it is also important to learn from your own mistakes. After all, metal corrosion does not happen by accident. This process begins only when the environment corresponds to certain conditions, to which the combination of access of oxygen and high humidity invariably belongs. With this in mind, try to keep metal objects in a suitable place, taking timely preventive measures.
