How to remove rust from stainless steel

Stainless steel is known for its resistance to rust and has long been widely used in all aspects of home life. Whether it is doors and windows or kitchen appliances, stainless steel can be seen everywhere. However, stainless steel is not rust-proof. If it is used for too long and is not properly maintained, stainless steel will develop rust spots. There are many tips for removing rust from stainless steel in life, and I will share them with you below.

1. Why does stainless steel rust?

Stainless steel has strong anti-oxidation ability and strong corrosion resistance in acid and alkaline environments. Because the material itself contains a thin oxide film, it can prevent the penetration of oxygen ions. Once it is damaged, most of the iron atoms will appear and rust will appear.

2. Environment in which stainless steel rusts

1. Cement and alkaline water: Cement, alkaline water and lime water used in decoration will corrode stainless steel sinks. We remind you to pay attention to timely maintenance measures when the decoration is not completed.

2. Iron nails and iron wires: The iron nails and iron wires used in decoration stay on the stainless steel material for a long time. Over time, a layer of decay and yellow spots will form on the surface. If they are not cleaned for a long time, they will turn into rust.

3. Chemical products: Paint contains a lot of chemical components, household cleaning agents, etc., which will accumulate on stainless steel plates over time and cause rust.

3. Tips for removing rust

1. Scrub with toothpaste: Some rust marks may be larger, we can try the magic of toothpaste, follow the grain, apply force evenly, control the strength, until scrubbing clean.

2. Use acidic reagents, such as fruit acid, acetic acid and other acidic agents to make the surface oxidized metal and the acidic agent react chemically

3. Use alkaline reagents, such as baking soda. The oxidized metal can be dissolved in the alkaline reagent to form a hydroxide compound.

4. Wipe the stains with 15% acetic acid solution (15% tartaric acid solution can also be used) or soak the stained part in the solution, and rinse it with clean water the next day.

5. Moisten the stained area with 10% citric acid solution or 10% oxalic acid solution, then soak it in concentrated salt water, and wash and rinse the next day.

6. If white cotton or cotton blended fabrics are stained with rust, you can take a small grain of oxalic acid (available at pharmacies) and place it on the stain, drop some warm water on it, rub it gently, and then rinse it with clean water. Be careful to operate quickly to avoid corrosion.

7. The easiest way: If you have fresh lemon, you can squeeze out the juice and drop it on the rust stains and rub it with your hands. Repeat several times until the rust stains are removed, then wash it with soapy water. Alternatively, you can first soak the rusty area with boiling water, apply sour milk, and then apply soap to wash it clean.
