Floating rust remains in the stainless steel water tank for a long time, causing electrochemical reactions; vegetable juice, noodle soup, acidic liquid, etc. adhere to the surface of the stainless steel water tank, which corrodes the metal surface; acid, alkali, and salt substances adhere to the surface, causing local corrosion; When it encounters condensed water in polluted air, it will cause chemical corrosion. The specific content is as follows:
1. Generally, stainless steel sinks will rust because of floating rust on the surface. Floating rust is some metal substances, organic substances and acid-base chemicals that remain in the stainless steel sink for a long time. The condensed water between the stainless steel sink and the stainless steel sink for a long time will The two are connected into a micro-battery, which triggers an electrochemical reaction, and the protective film is destroyed, which is called electrochemical corrosion.
2. Vegetable juice, noodle soup, acidic liquid, etc. adhere to the surface of the stainless steel sink. Organic acids will corrode the metal surface for a relatively long period of time.
3. The surface of the stainless steel sink contains acids, alkalis, and salts (such as alkaline water and lime water splashed on the wall for decoration), causing local corrosion.
4. In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, and nitrogen oxide), when it encounters condensed water, it will form liquid points of sulfuric acid, nitric acid, and acetic acid, causing chemical corrosion.
How to Remove Rust Spots from Stainless Steel Sinks
1. Toothpaste, which is often used in our daily life, is an excellent prop to remove rust spots. First, soak the part of the sink with rust spots in water, then apply toothpaste on the prepared soft cloth, and then use a soft cloth to clean it. Repeatedly add water to wipe the rust spots until the rust spots are clear and clean.
2. We can use homemade cleaners to clean up rust spots. First rinse the rusty spot with clean water, then sprinkle lemon juice on the toilet paper, cover the rusty spot with the toilet paper, wait for ten minutes, then remove the toilet paper, then sprinkle baking soda on the rusty spot, and finally use an old toothbrush Wipe it over and over again.
3. On the market, there is a special cleaning agent for cleaning rust spots on stainless steel. It has obvious effects on cleaning rust spots on stainless steel, sinks, and range hoods, and the most important thing is that the price is quite cheap. But it is best to be able to buy branded products, so as not to buy fakes, and the effect of cleaning is not obvious.
4. Using white vinegar can also remove rust spots in stainless steel sinks very well. This is because white vinegar contains a large amount of acetic acid, and this acetic acid will chemically react with rust spots to achieve the function of removing rust spots. When in use, just sprinkle white vinegar evenly on the rusty surface, and add some salt.
