If these are silver coins DON'T clean them!! There are collectors out there who LOVE to buy "toned" coins and will pay extra for that.
If you use some kind of cleaner, what you are actually doing is removing some of the coin - and you will be left with something that is then unattractive to a coin collector.
You should be happy that the coins you have are now toned - don't try to fix something that isn't broken! And on top of that - if you try to sell them, you can tell the history - they were damaged in Hurricane Katrina and thus may gain even more profit!
From pcgs website:
toning
The term for the color seen on many coins. There are infinite shades, hues, and pattern variations seen, the result of how, where, and how long a coin is stored. Every coin begins to tone as it leaves the die, as all United States coins contain reactive metals in varying degrees.

If You Have To Ask - Definitely Do Not Clean Them!
It's true that if you had to ask about cleaning your coins, how to, or whether to, then the best thing for you to do is nothing. Don't clean them. You will almost certainly not improve them, and you are much more likely to spoil them.
