Being new on this forum I have not yet gone threw the many posts concerning cleaning of coins. I know that cleaning is not recommended for highly valued coins. The problem I am having is years ago I placed many of my silver dimes and half's (luckily not my few dollar coins) in the manila colored paper flips. Getting the coin collecting itch once again I checked my coins and the ones in these flips are tarnished from I guess the chemicals in those flips. I purchased some E-Z-Est coin cleaner and tried one dime. Dipped only a few seconds and the tarnished removed immediately and the coin looks nice at least to the eye. After reading some posts about this stuff and how it can actually hurt the surface I was wondering if there is anything safer to remove this type of tarnish that these flips produced? I am not sure what was used in them, but they caused the coins to turn dark.

Not recommended for ANY coins. I would leave them alone, period.

Post some pictures of the tarnished coins. Some collectors might like it and pay a premium for them.

To the place for coin cleaning.
Depending on how bad the toning, tarnishing or whatever is on those coins is, you may not want to chance any cleaning at all. Remember that the darkening of any coin is usually due to the outer layer of the coin's metal with another substance. Sulfur, Oxygen, Chlorine, etc. Regardless of what caused the discoloring and/or darkening, when that is removed, so is some of the original metal of the coin.
As an example with old, antique furnature, some people samd them all down to make them look pretty. This usually completely ruins them due to the loss of the original material. Similar with coins. It is always best to leave them alone and as is.
Dipping in the stuff you used is sort of like Tarn-X, Jewery Cleaners or even a strong acid.
Since the subject of cleaning coins comes up so often, you could try the Search tab at the top for coin cleaning, cleaning coins, Acetone, etc.

There is a distinction between cleaning and conservation. A good rule is that if you have to ask, then you should not try it. This is not to say that you should not ask, but be prepared to do some serious learning before taking on any experiment.
