Many faucets have been used for more than ten or twenty years. This is not surprising, but current faucets are not necessarily as long as old-fashioned faucets. They are said to be stainless steel. But the faucets are rusty and most students have seen it. Why does it rust, and how to remove rust from the faucet?
Causes of rusty taps
Assuming that your faucet is made of stainless steel, the so-called stainless steel is not rust-resistant but rust-resistant than iron. Among them, nickel and chromium are among them. It is very normal that rust occurs when forming a primary battery in the presence of water. This layer of rust is concealed on the outside of the faucet and it loses its luster, and the outside is very unsightly.

In the 1950s and 1960s, drivers who drove cars, motorcycles, and trucks used Coke in the industry. Phosphoric acid is still used for the above purpose, and all anti-rust coatings require phosphoric acid.
9. Iron rusting requires water and oxygen. The solubility of gas decreases with the increase of temperature. In other words, the solubility of oxygen in hot water is relatively small-hot water contains less oxygen but cold water It contains more oxygen, so the cold one will rust faster.
