Read the article about how to remove rust from metal at home using folk remedies.

How to clean the surface?

To achieve a good result, rust removal must combine an integrated approach: mechanical and chemical action.

Just cleaning off the rusty layer is not enough. Chemical exposure prevents the spread of corrosive processes.

In addition, electrochemical action can be used by passing an electric current through a special solution. This method is used more often in industrial settings, but can also be organized at home, despite the complexity of the organization.

You will find all the most useful and important information about methods and techniques for removing rust in this section.

Acids

Let's look at what acids remove rust:

Lemon

foto21224-2Citric acid is a harmless product that will help deal with rust stains on metal, as well as on tiles and other surfaces.

At the stage of preparation for cleaning the acid is diluted with water, preparing a concentrated solution, and applied to the affected areas.

After the composition has been applied for an hour, the acid is washed off with a washcloth. This option is suitable for light stains, but will not cope with serious ones.

  1. With a rag soaked in acid, rub the surface with areas of corrosion using polishing, rubbing movements.
  2. Leave for half an hour.
  3. Wash off with plenty of water.

You need to wash off the acid especially carefully so that it does not remain on the metal at all, since it can damage the skin of your hands, even in low concentrations. It is necessary to take into account the toxicity of the drug and pay attention to personal protection.

Orthophosphoric

Phosphoric acid is one of the most effective substances for removing corrosion on metal.Due to its ability to react with corrosion products, this drug can cope with even significant damage.

To clean the metal, an acid of 15-20% concentration is used. The time required for exposure is about 5 minutes. After this, the remaining rust is cleaned off with a stiff brush.

Phosphoric acid is included in most rust converters. He will tell you about the use of phosphoric acid against rust. this article.

Vinegar

Removing rust using vinegar is a simple method that does not require significant investment. But This method will give a good effect only with unstable stains. in domestic conditions, for example, in plumbing.

The best results will be if the rusted metal objects are small and can be completely dipped in vinegar. This method is convenient for bringing bolts, nuts, etc. into proper shape.

It is recommended to use vinegar undiluted. Read more about the cleaning method Here.

Soda

foto21224-4Baking soda is an affordable drug to combat rusty plaque. at home.

To prepare the cleaning composition, you need to make a non-liquid mixture, the consistency of which is like gruel.

Operating procedure:

  1. Using a sponge, apply the composition to the area of ​​contamination using rubbing movements.
  2. The mixture is left to act for half an hour.
  3. Rub the metal again with a sponge or brush.
  4. Rinse off.

Hydrogen peroxide

Peroxide is a cheap pharmaceutical product used to disinfect wounds. In addition, this drug is actively used to remove dirt from various surfaces, and also helps to cope with rust.

You can use peroxide as a stand-alone product or in combination with sodium salt, which can increase the effect.

Procedure:

  • pour 4 tbsp into the prepared container. trisodium phosphate;
  • pour in 3 liters of water;
  • pour in 50 ml of peroxide very slowly, in small portions;
  • Dip rusted tools or other metal objects into the container;
  • leave the metal in the solution for half an hour;
  • wash off the composition with water.

For large objects, active rubbing of the metal surface with a solution is acceptable. Periodically, several times, every 10 minutes, repeat rubbing.

It is convenient to use peroxide to combat corrosion if it is present in small volumes, for example, on kitchen utensils.

Aluminium foil

foto21224-5Aluminum foil, which is used in the kitchen during food preparation, can be used for an abrasive effect.

To do this you need:

  1. Cut off a small piece of foil.
  2. Form this piece into a ball.
  3. Use this ball to treat rust stains using rubbing movements.

This method can be used to treat small stains, but it is not suitable for eliminating serious corrosion damage. Treatment with foil gives an unstable result.

This method is suitable as a temporary measure, if necessary, remove local traces of rust, for example, on the iron.

After using only aluminum foil without the use of additional products, the result will not last long - no more than a few months.

Cola

Using Coca-Cola for Corrosion is a Popular Cleaning Recipe. In order to get a noticeable result, it is necessary to ensure contact of the cola with the metal surface.

If you need to process metal that is fixed at an angle or vertically, you can soak a rag with it and apply it to the desired areas.

Depending on the extent of the corrosion processes, exposure should last from several hours to a day. After this, the surface is brushed and washed off with water.

The effectiveness of the recipe is due to the phosphoric acid contained in cola. Read more about this method of cleaning surfaces from rust in this article.

Battery

Even a regular battery can be used to remove rust. To carry out the work, you need to prepare tools and consumables.

You will need:

  • foto21224-6salt batteries with a zinc body;
  • rubber gloves;
  • blade;
  • insulating tape (or rubber band);
  • baking soda;
  • the wire;
  • sponges;
  • car battery;
  • electric clothespin (optional);
  • orthophosphoric acid.

You can check that the battery is a salt battery with a zinc case using a magnet - it should not be magnetized.

Work order:

  1. Use a razor blade to remove the wrapping from the battery.
  2. Wind the wire around the body, securing it with electrical tape.
  3. Attach the sponge with electrical tape to the end marked “-”.
  4. Remove rust from the metal that will be processed.
  5. Soak the sponge in phosphoric acid.
  6. The battery wire is connected to the “+” side of the car battery. This can be done conveniently using an electric clothespin.
  7. Burning off rust is carried out by pressing the end part of the battery, which has a cotton pad on it. Hissing and the appearance of foam should indicate that the process is proceeding correctly.
  8. During the processing process, the cotton swab burns out and must be replaced.If a large area of ​​metal is to be processed, then the battery will also have to be changed.
During the processing process, you cannot linger in one place. It is necessary to drive over the source of corrosion, ensuring the removal of rust and the transfer of zinc to the surface.

After galvanizing, the acid must be removed. Soda is used for this. A concentrated aqueous solution is prepared from it, which is used to wipe the surface.

After this treatment, the metal will be protected and will not rot. Even if significant damage has already been caused by corrosion, further spread of the process will be stopped.

Prevention of corrosion

foto21224-7To prevent corrosion from damaging the metal, it is necessary to pay attention to preventive measures.

Surfaces without an external coating are most susceptible to corrosion.. In humid conditions and with access to oxygen, such metal rusts very quickly.

The solution to the problem is timely care of metal elements, which would prevent the growth of corrosion processes. After removing the rust, it is advisable to protect the surface from moisture with a coating.

7 recommendations

In order for rust removal using home recipes to be effective, The following recommendations should be taken into account:

  1. If the result was not achieved the first time, cleaning should be repeated.
  2. When choosing a recipe, you should consider the type of material that needs to be put in order. Not all recipes that are suitable for caring for metal can be used on plastic and other surfaces.
  3. Work to remove rust must be carried out wearing protective equipment. Even when cleaning is done simply with vinegar, gloves are needed.If caustic substances that produce toxic fumes are used, it is necessary to additionally use a respirator and safety glasses.
  4. When choosing a cleaning method, it is necessary to take into account the degree of corrosion processes. For advanced cases, many methods will be poorly effective, for example, with soda, vinegar, foil.
  5. After chemical exposure, the rust must be removed with a stiff brush or metal scraper.
  6. In advanced cases, when the top layer of metal is damaged by rust, the surface must be prepared for chemical attack by cleaning off the top damaged layer. To do this, scrapers, brushes with metal bristles, grinders and other devices are used.
  7. To remove rust from car metal, it is advisable to use rust converters rather than homemade recipes.
Only ferrous metals can be subject to corrosion; the process does not apply to non-ferrous metals. But they may still have drips and rusty stains from other metal objects.
