General rule that is always stressed with newbies is don't clean your coins. This is done because until you have some experience evaluating a coin and deciding if foreign material can be removed and how it can be done safely without doing damage to the coin, it is way too easy to just jump in and do things that are inappropriate that end up doing further damage to the coin instead of protecting them. The topic of PROPER cleaning/curating is involved and complex, and no one thing works for all coins in all cases. So each coin has to be evaluated separately. Most newbies want to just jump right in and do SOMETHING to them, and it is MUCH easier to damage a coin than improve it. That is why we always start with that big DON'T!.
I hope that was gentle enough.
