i asked at a few forums, one of them the mothers wax forum and i was told stay away from any bleach products specifically. That after telling them i wanted to be sure i don't use anything that may cause cracking, which is my only real concern. I don't mean to sound like i'm doubting you guys, but who do i believe? i really don't know what to believe when being told the opposite from different sources. i don't put any more stock in any of these opinions than the other, but i have no idea which way to go....bleach or no bleach. Guess i'll just wait for more replies and see if theres some general concensus.
