The One Pound coin does not rust, it is made from an alloy of nickel and brass which are both non-ferrous metals and therefore iron oxide (rust) cannot develop.

If the coin has any collector value, such as a Proof coin, DO NOT CLEAN IT.

If the coin has no value other than its face value and is just something you would like to look nice and keep, try any of the commercially available jewellery cleaners or, drop it into a glass of fizzy soft drink for a few hours. There is sufficient acid in a soft drink to take the average crud off most coins, but the finish of the coin will suffer.
