Don't try anything like coke or an acid, in fact never clean a coin. It will destroy the value of the coins. If you have any that are worth a lot of money, then get hold of Numismatic Conservation Services. www.NCScoin.com. They are the pro's in this field. Cleaning by non professionals, will most of the time either destroy the coin or make it valueless. Most ancient coin are cleaned by using olive oil but it takes a long time. Inexpensive ancient coins like some Chinese cash can be cleaned using a weak acid, then put in baking soda to stop the action of the acid.

If they are American coins, there is little you can do except get a professional cleaner to clean the most valuable ones. You can always make a warm water bath and soak them for a bit and scrub with a PLASTIC scrubber, (no metal), and then dry as soon as possible. This will not do any harm. Water should not have damaged silver or gold coins, (it may have tones the silver, but that is ok), but the copper may have been ruined. Copper reacts and forms a "crust", which actually partially destroys the coin. You may have a nasty surprise when you wash them that part of the copper coins have been "eaten". Not much to do about it I am afraid, but a professional can make it look better. Like I said, send to a professional cleaner anything of any real value, (over $100 I would say).

lots of stuff "cleans" coins. best choice, obviously, depends upon the type of contamination. If the coins are rare and/or valuable, consult a professional.

I have restored Roman coins by soaking them in olive oil. You may need to change the oil several times, but it worked for me.

if they were precious metals then they wont oxidize. The metal coins you can try soaking them in coke. Mythbusters proved that it is great for cleaning coins.

You'll laugh at this but it works.
Leave the coins in Coca Cola overnight, they will come out like new!

if salt water got on them then that is a problem. Contact a reputable coin dealer for advice.

My grandpa uses hot sauce.It always made them like new. Even those old crusty pennies I used to give him thinking they were special cause they looked old. It stinks though.
