If an external protection (primer, paint, etc.) has peeled off or peeled off from a pipe or other iron product, this place will necessarily be covered with rust. Rust is nothing more than various kinds of iron oxides. Iron, when exposed to air with any minimum degree of humidity, begins to actively react with oxygen and water vapor, thus forming oxidation products. How to get rid of this scourge at home using improvised means?
Danger of untimely rust removal
Rust is a brown substance with a porous structure, which makes it able to absorb and retain moisture, thereby further aggravating the situation and accelerating corrosion. Therefore, it is not necessary to bring the foci of rust to critical scales, but at the slightest manifestation of them, clean and preventive measures for processing metal parts subjected to corrosion.
Rust Removal Methods
Since rust is a porous oxide that does not hold too tightly on the main, non-corroded part of the metal, it can be removed using the following simple methods:
- The mechanical method, which is based on the cleaning of metal parts from rust with a metal brush or sandpaper.
- Chemical, using special solutions created on the basis of sulfuric, hydrochloric and other acids. Acids actively react with any iron oxides, and so that the acids do not destroy the metal itself, special inhibitors are added to the solution, under the influence of which the reaction with pure iron does not occur.
- A protective method based on the use of metal surface converters. In fact, it does not remove the rust itself, it simply makes the further oxidation process impossible.
How can I remove rust at home? Some simple tips
It will not be difficult to remove rust deposits at home if you have at hand:
- diesel fuel;
- vinegar;
- lemon acid;
- soda.
The process of removing rust, depending on the means used, has the following form (pictured). How to deal with it:
- In the case of diesel fuel, it is necessary to place the rusted part in a tank with diesel fuel for at least 2 hours. If the part cannot be removed, a cloth in diesel fuel can be abundantly moistened and wound around a place covered with rust. After the rust is easily cleaned from the part with a stiff (preferably metal) brush. Wipe with a dry cloth and the part is clean.
- The method with table vinegar is the same as in the case of diesel fuel.
- We apply citric acid to the part, wrap it with a cloth moistened with water and leave it overnight. If the part or object is removable, you can put them in a container in the evening, pour rusty places with citric acid and pour warm water. In the morning, all that remains is to get out the part, rinse and wipe off any remaining rust with a dry cloth.
- Rust is a kind of “spraying” on the surface of a metal. It is easy to remove with gruel made from baking soda and water. We apply the gruel in places with rust, leave for a couple of hours, and then clean it with a rusty “dusting” with a rag or brush.
Conclusion
We hope our material on how to clean rust turned out to be useful to you. Of course, in industrial conditions, all this is done with the help of special tools and chemicals, but in order to get rid of corrosion at home, these methods will be enough. The main thing is not to forget after cleaning the part and installing it in its place, treat it with anticorrosive substances or apply a layer of a special primer on it. Otherwise, after some time, the rust will reappear.
