If you don't believe me, just ask the inventor, Mr. Brillo:
We are still trying to figure out where he came up with such a good idea.
Maybe his wife, Mrs. Brillo:
Maybe we'll never know,

Realone is correct, I thought this questions was a joke question so I made a joke, but the bottom line is there is only one in a few hundred thousand coins that should be cleaned, the rest should be left as they are.
I think the number is like 1 in 374,683.7 coins that can/should be cleaned.
Did you know that 99% of all statistics are made up on the spot?
