As was already written here you should not clean the coin at all. If it is toned just leave it alone. if it has a high value you will lose money cleaning it. Now if the coin is not very valuable and has just some oils or grease on it, they can come from the mint that way. Then dip coin in acetone, that should dissolve the oils and grease (also good for glue). Do not wipe the coin the gunk must dissolve by itself. Then put coin in distilled water and let air dry. Only do the above if the coin is not worth a lot and the problem is oil,grease or glue. it won't help with anything that actually ate into the coin. In the end the best thing is leave it alone unless by doing so may cause more damage, that being the case see a couple of coin dealers for their opinion. coin club members can also help especially the old timers.

Never clean a coin ,let a professional do it .
Abrasives will scratch the coin and certain cleaners and solvents remove protective layers of metal .
Find out if the coin is even valuable before you seek to clean it . If it is a common coin (silver ) they will only pay a scrap price anyway .

As a longtime collector, I would advise against cleaning. Patina is all important. Cleaning will alter -- usually reduce -- value of any coin. Whatever you decide, DO NOT use vinegar or toothpaste or any of the home remedies many here will recommend. The famous silver cleaner you buy at Walgreen's -- the dip -- is corrosive and will harm the value of a coin.

DO NOT do that. It will damage the coin and it will lose it's value.
