How to Remove Rust from Metal

So how to remove rust stains from metal?

What is Rust?
The process of oxidation is popularly known as rusting. One of the disadvantages of metal is that when it comes in contact with oxygen for a period of time, the oxygen gets the better of it and the metal rusts. Talk about bad company. When oxygen comes in contact with a metal like iron or aluminum, it oxidizes the metal to form a compound from what was previously an element. So the resulting compounds are iron oxide, aluminum oxide etc. The process of oxidation is usually a slow one unless acted on by a catalyst. A catalyst is something that helps speed up a chemical reaction (in this case oxidation). Substances like water act as a catalyst to oxidation, hence we see that a lot of rust accumulates on pipes etc.
