So the question is, how to you clean this gunk off the pad?
The answer is there’s a number of ways to clean your foam pad, the three most common are,
Pad Washer
Nylon Brush or Pad Cleaning Brush
Terry Cloth Towel
Thanks BobbyG I read this article before posting this thread and it left me with the question how often do I clean it? Is it when I see paint on my pad? or every section I buff out? Im a bit confused on that part if that helps clarifying things.
