Corrosion is the environmentally-induced destruction of metals and alloys. Rust is a product of iron’s corrosion by oxygen and water. The presence of salts, such as salty sea water, may accelerate the appearance of rust. During corrosion, iron turns into iron(III) oxyhydroxide:
Fe + 2H₂O - 3e⁻ = FeO(OH)↓ + 3H⁺
Rust forms a rough coating with a flaky structure. It has a distinctive color range from orange to red-brown. Objects covered with rust may give out over time. All three of these solutions contain different acids, which react with iron(III) oxyhydroxide to form iron salts and water. Professional rust removers are designed to fulfill this function and do so perfectly well. But if they are not at hand, then lemon juice or table vinegar (9% solution) can cope with rust just as well! They are cheaper and can be found in just about any kitchen. After cleaning the rust off your tools, store them in a dry place to prevent further corrosion.
