Is there a right way to clean a coin so as not to damage it?

Ahhhh.  Please be careful. Most coins cleaned by new collectors are ruined.

Cleaning method depends on the issue to be solved.. .
 
Bad toning?
Haze?
PVC damage?
Gunk?
Residue?
 
There are cleaning solutions, but these can be harmful to you and the coin.
 
Don't use anything abrasive no matter what, this will alwats damage a coin.
 
Here's one article... most people don't RUB the coin, but some use acetone as the first rinse (harmful chemical careful): http://coins.about.com/od/caringforcoins/ht/cleancoins.htm

Concerning cleaned coin's If I were to have to use an acid bath on a 3 legged buff to show date is it considered cleaned or what catagory does the acid place the coin? Probably only good for filling a space in a folder or something collectible right?

Acid cleaning is considered harsh cleaning and damaging.

Please note I am opposed to most cleaning, as it generally ruins coins.

You have to take into consideration that cleaning is a relatively "new" bad thing. Almost all 19th century and older coins have been cleaned at some time or another.
 
For the most part, a light cleaning will be accepted.
 
Cleaners like jeweluster and dips remove the luster, and make the coins look cleaned.
 
A very mild solution, will more often than not be overlooked.

Items like this should be a permanent post. Cleaning coins is probably the most discussed item I have ever seen of this or any forum. There could be list of methods used and why they could, should or not be used.
As for using any type of acid, always remember that whatever acid removes also contained some of the coins metal. The more metal gone, the less value the coin. Another important item is using acid is just not safe for your eyes.

I don't recommend any cleaning be done by a collector unless lots of practice on similar low cost coins has been done.

Generally I recommend using a service like NCS for coins worth more than $50 or coins that are sentimental and are invaluable.

To coldshot.......
If it is truely a 3-legged Buff there are other tell-tales signs that graders use to verify the coins & they would use those to verify date.
Using 'Nick-A-Date' or some other acid to bring our the date will surely reduce the value, probably a lot.
