Clay bar question.....
 

Okay, I've read through posts and have seen them get used and get really nasty and dirty.

What in the world do you use to clean the clay bar? Is it a one time use thing?

You don't clean it. As it gets dirty, you fold it over and kneed it. After a few uses, you replace it.

I use 1/4 of a clay bar to do my car, then I throw it away.
