I'm New. To Clean Or Not To Clean My Coins

DO NOT CLEAN COINS.

Don't clean your coins, but it's OK to soak them in oil?

Do NOT soak them in anything except warm water and mild dish soap, and in fact, don't do that, either.

Do NOT rub them with your thumbs under running water, or a soft cloth, or anything else.

Whenever you see the 'need' to clean your coins, lay them out on a table, look at them, and repeat this phrase "I am my own worst enemy", followed by "I am your friend, as I am a friend to all coins. I would never harm you." When you have calmed them down and soothed their fears, put them away until next time.

It is odd to many people why some things should be cleaned and others no. For example you clean your car, house, bike, etc. But you don't clean coins or anything that is a sort of collectable. However, there are those professionals that clean old old paintings. Yet with very old furniture, it is best to leave as is. Confusing, isn't it?
