How to deal with metal rust and how to wash off the rust on the metal

Different metal rust removal methods are also different, in general, there are only two methods of rust removal, one is chemical rust removal method and physical method. For example, if iron rusts, with chemical rust removal method, different concentrations of acid can be configured to remove rust, but at the same time, there will also be some corrosion on iron. Physical rust removal method, using steel brushes or sandpaper and angle grinders to remove rust.

After removing the rust by the above two methods, the derusted iron must be treated with anti-corrosion treatment to prevent rust again.

The frame can be treated separately, sandpaper to polish the rust, then clean the grease, spend a few dollars to buy a can of black self-spraying paint to spray it locally, pay attention to do a good job of protection, masks are essential, and pay attention to the brake disc next to it not to spray, let alone the exhaust!!

Generally, if the metal surface is rusty, it is recommended to sanding it by sandpaper, and then remove the rust, and appropriately choose polishing or add some outer coating for rust prevention.

Aluminum products: Soak the aluminum products with black spots in the vinegar dilution, take them out after about ten minutes, and rinse them with water to remove rust.

Copper products: use a cloth dipped in vinegar, then add fine salt grains to rub and rub, and finally rinse with water to remove rust.

gold and silver jewelry; Directly soak the jewelry in dilute acid for a few minutes, and treat it with water after taking it out, so that the jewelry is as clean as new.

Dry powders can be bought online specifically for treating metal rust, and as long as a little powder and a little water are rubbed, the rust will fall off.

What to do if the metal rusts? Let's teach you the easiest way to deal with blackening.

1. Lemon juice and salt: Sprinkle salt on the rusty metal first, cover the rust thoroughly, and then pour the squeezed lemon juice; After waiting for 2-3 hours, scrub the mixture together on it. The acidic components of lemon juice can react with rust to remove rust.

2. Acidic solution: 10% citric acid solution or 15% acetic acid solution is sprinkled on the rusty part of the metal, or the metal can be directly soaked in the solution, wait for a day, take out the metal and wash it with water, pay attention to the acidic solution has a certain corrosiveness, avoid contact with hands.

3. Baking soda and water: Add a small amount of water to baking soda to mix to form a thicker paste, and then apply it to the rusty parts of the metal. Wait 1 or 2 hours for the paste of baking soda to condense, then use a brush to scrub the mixture on the metal in the water, and the rust is gone.

1. Use white vinegar. Vinegar dissolves the rust layer on the surface of the metal. Soak the rusty metal in white vinegar for a few hours, then wipe off any remaining rust stains.

If the metal object is too large to soak in white vinegar, pour a layer of white vinegar on top and leave it for a while. You can also wipe off rust stains with a rag soaked in white vinegar.

Try dipping the white vinegar in tin foil and scraping off the rust layer. Although the friction of tin foil is not as good as the steel wool used for brushing pots, it can also remove the rust layer.

Ordinary vinegar can also remove rust. Soak the rusty metal object in it and rinse it off after 24 hours. In this way, there is no need to wipe hard.

2. Try lime and salt. Sprinkle the salt over the rusty area, then squeeze out the lime juice and pour over the salt. The more lime juice you have, the better, then let it sit for 2 to 3 hours before scraping off any remaining rust stains.

Use lime peel to wipe off any remaining rust stains on the metal. It effectively removes the rust layer without damaging the metal surface.

If you don't have lime, you can also use lemon instead.

3. Use potatoes and dish soap. Cut the potatoes in half and soak the cut side in dish soap. They react chemically with the rust layer, making it easier to remove. Place the potatoes on top of the rust layer and let them sit for a few hours.

If one time is not enough, simply cut off the used part of the potato, soak it in dish soap and continue to place it on top of the metal.

If you don't have dish soap, you can also use baking soda with water instead. [1]

There are many ways to remove rust from metal surfaces, and for different kinds of metal materials, the rust on the surface is different, so the methods of rust removal are also different. On the other hand, different surface engineering technologies, such as electroplating, coating, etc., have different requirements for surface rust removal. Therefore, when actually choosing a rust removal method, it is necessary to choose the appropriate rust removal method and process according to the type of metal materials and the requirements of specific surface engineering.

Commonly used surface rust removal methods include chemical immersion method, ultrasonic method, electrochemical rust removal method, mechanical method and manual rust removal method. 1.Chemical immersion method Chemical immersion method is to soak the metal workpiece in the corresponding rust removal solution, and use the acid, alkali and other chemicals in the solution to react with the oxide scale and rust products on the surface of the workpiece, so that the oxide scale and rust products are dissolved into the solution, so as to achieve the purpose of rust removal.

Chemical immersion method is a commonly used rust removal method for small workpieces, with fast rust removal speed and obvious effect, especially for parts with complex shapes, it can remove some rust in the dead corners such as inner holes and inner cavities.

It is not easy to remove metal rust, so it is best to pay attention to preventing metal rust.

The treatment method of ferrous metal rust is as follows:

1. Physical method, use steel wool ball to brush or sandpaper to polish until bright, in short, try to remove the rust.

2 chemical method, use an acidic solution that has been diluted to a lower concentration, such as white vinegar, and wipe dry with a cloth after cleaning.

3. Use rust removal powder.

Vinegar can remove rust from the surface of the metal, put the rusty metal in white vinegar, let it stand for a few hours and then wipe off the remaining rust stains. If it's too big to soak in white vinegar, pour a layer of white vinegar on top and let it sit for a while. You can also wipe off rust stains with a rag soaked in white vinegar.

Lime with salt

First, sprinkle salt on the rusty area, then squeeze the orange juice and pour it over the salt, and finally let it sit for 2 to 3 hours, and finally scrape off the remaining rust stains, and use the lime peel to wipe off the remaining rust stains on the metal. It effectively removes the rust layer without damaging the metal surface. If you don't have lime, you can also use lemon instead.

Baking soda paste

Take out the appropriate baking soda, add water to the baking soda and mix it into a paste, apply the baking soda paste, leave it for a while, and then scrub it clean.

Potatoes and dish soap

Cut the potatoes in half and apply dish soap to the cut side. They react chemically with the rust layer, making it easier to remove.

Coke and vinegar scrubbing can remove rust.

The main component of rust is ferric oxide, which is an alkaline oxide. Coke is a carbonated drink, and the manufacturer adds a large amount of carbon dioxide to the water with a high-pressure device during production, and the carbon dioxide dissolves in the water and reacts with the water to form carbonic acid.

Therefore, in addition to rust, cola is actually an ionic reaction between the carbonic acid in cola and the iron oxide in rust state envy, and the iron ions in the iron oxide exist in the solution, and those bubbles accelerate the shedding of rust. Not only Coke, but also carbonated drinks such as Sprite and Fanta can remove rust.
