What liquids cause rust?

Rust is the name of the corrosion products of Iron.

Usually, i mean what we usually see in our life, like for example rust on nails, is caused by the reaction of water, or better the oxygen dissolved in water, with Iron.

Corrosion occurs when a metal is in contact with an electrolyte, a fluid that carries electricity; so every liquid that is a good electrolyte is corrosive towards iron.

The corrosivity of fluids is related to different factors, like for example its pH. Liquids that are acidic, contains acids, and have low pH are more corrosive.

Hot liquids are as a general rule more corrosive that cold liquids.
