Rust remover with metal: basic methods and materials
Rust is called appearing on the surfacemetal in contact with air and water oxide. Finding red spots on iron, steel, brass, etc. objects, measures should be taken immediately. The fact is that the oxidation process is progressing very quickly. Fortunately, there are many methods of removing rust from metal. The choice of a particular technology depends on the type of surface to be treated, the degree of its damage, and so on.
Basic Removal Methods
For metal surface treatment against rust, the following can be used:
- Anointing brush, brush or drill with appropriate nozzle;
- A special tool for removing rust from metal (paste, spray, liquid).
Like any other oxide, the corrosive layer is easily neutralized by acid. Therefore, this substance contains virtually any means for removing rust from the metal.
Machining by mechanical means
This technique is useful for removingmanifestations of corrosion from flat surfaces having a large area. In this case, the metal is thoroughly thoroughly cleaned of dirt. Then the red spots are removed using a drill equipped with a brush head or an abrasive wheel.
The treatment should be carried out until the appearance of pure metal. In hard-to-reach places, rust is removed using sandpaper.
Removal of purchased chemicals
Shop trays intended for cleaningmetal from rust, can be used in a variety of situations. However, usually all kinds of pastes and liquids acquire, if necessary, the processing of small objects of complex shape. When using such tools, as with the use of a drill, you should be as cautious as possible. Since all anticorrosive pastes and liquids contain acid, it is extremely undesirable to allow them to enter open areas of the skin.
When carrying out repair and construction worksAlso, you should use some chemical to remove rust from the metal. Before painting any kind of street and located in wet rooms, structures must be processed. Applying paint without first cleaning the surfaces in this case is simply pointless. Even under the paint, the oxidation process will continue.
This technique is suitable for the purification ofany metal objects. To remove rust in this way, you need a current source and an electrolyte. The latter is poured into a plastic bucket. There, too, place the object to be cleaned. Next, a positive contact is connected to the electrolyte, and a negative contact to the metal (so that it does not come into contact with the liquid).
After applying a voltage in the bucket, an electrochemical reaction begins, which results in separation of the oxide and settling it to the bottom.
How to clean rust from the car body
Red spots appearing on metaldetails of the machine, it should be cleaned as quickly as possible. Most car enthusiasts know that if there is rust on the car's body, its cost is reduced by about 2-3 times. The replacement of the corroded parts is very expensive.
There are several ways to clean the car body. Most often, for this purpose, a strong concentrated liquid agent is obtained to remove rust from the metal.
Sometimes damaged body parts are treated andby dilute orthophosphoric acid. Another good way to get rid of red spots on the car is to use a mixture based on zinc salts. In this case, an electrochemical cleaning method is used, but, of course, without the use of a container. The mixture is simply applied to a rag wound around the electrode. Next, the latter is connected to the battery.
Comparison of car rust removal tools (purchased)
Various kinds of compounds designed to fightwith corrosion, today there are many on sale. For the treatment of large parts of the car - the body or engine, for example, often used means "Dezoksil." Its main component is the surfactant acid.
In addition, very good reviews are available aboutliquid "Anti-rust NEOMID 570". It can also be used for bodywork or engine treatment. Praise this tool for removing rust from metal auto, among other things, also because it can be used to clean not only light new, but also old spots. In the latter case, either a concentrated liquid or a diluted liquid should be applied to the surface, but in several layers. Half an hour after treatment, the composition should be washed off with water.
Even more pronounced effect when cleaning partscar can be obtained by using a domestic rust remover with metal "Zinkar". After treatment, this formulation leaves a complex protective film on the surface. It is "Zinkar" for today can be considered the best anti-corrosion agent for metal surfaces.
Small chrome car parts usuallyclean with the use of not a liquid, but a special paste. Very good for this purpose, for example, is suitable Metall Polish from the company "Avtosol". This paste is simply applied to a rag, after which the part is rubbed until the oxide is completely removed.
Cleaning of kitchen accessories
Any means for removing rust from metal onthe car usually contains a very large amount of acid. Therefore, for the processing of objects used in everyday life, it is worthwhile to use other, more sparing formulations. On sale today are available in the number and specially designed for this purpose sprays and liquids. With their help, you can easily clean steel sinks, chrome parts of kitchen sets, dishes, etc.
Very popular with housewives is, for example,means for removing rust from metal "Adrilan". Judging by the feedback, it is possible to remove oxide stains from different surfaces with its application, practically without straining. At the same time, it is allowed to use Adrilan for cleaning not only metal, but also enameled surfaces. Very good reputation for housewives also use such rust converters as "Omega-1", Avs Avk and Runway.
Popular methods of struggle
Next, let's see what kind of toolto remove rust from metal at home is best. In this case, by the way, different methods can be used. So, for cleaning steel and cast iron objects, soda is most often used. From it, you should make a thick slurry (adding water) and smear it with a surface. After about half an hour, the treated object needs to be wiped with a stiff brush or a wire washcloth.
In addition to soda, for cleaning metal surfaces from rust, you can also use:
- Ketchup. It is applied to the affected area, and then wipe the surface dry with a clean rag.
- Lemon juice. This tool is used in the same way as ketchup.
- A mixture of vinegar and salt. With the use of such gruel, even old rust stains can be removed.
- Food foil. It must be crushed into a strong lump and rubbed with a stain.
Also, if desired, you can use such an inexpensive means to remove rust from the metal at home, as mixed with a large salt of grated potatoes.
It happens that the red spots do not appearonly on steel vessels, but also on cast iron. In this case, vegetable oil is usually used for surface treatment.

Brass, like steel, from rust is bestclean with a mixture of vinegar (120 g) and salt (1 h / l). In gruel it is worth adding a little flour. After 30 minutes, the paste applied to the metal should be washed off with warm water.
Aluminum from rust is quite simpleclean with Alka-Seltzer. Acquired tablets should be dissolved in water in some kind of container and lowered into the liquid in need of treatment.
How to prevent corrosion
