Blueblast, theres nothing that I know of. Maybe someone else is. But this is why I have so many engine/exhaust microfibers now, lol. This is also the reason why I dont recommend microfiber wash mitts, b/c once it grabs the dirt, they just dont want to let go.
porschefan, I use microrestore on my foam pads all the time. I pour some MR in a bucket w/ some warm water, then clean them in there, rinsing under clean water. I havent noticed any problems yet.
