the thing that i thought about was the fact of using one chemical to clean another and the residue it might leave behind, if any at all. if that stuff works then all the better. i think kuri was trying to find out if it had natural ingrediants so he could make his own version, and that sort of interested me as well. thats when the whole idea of plain water entered my mind. and im sure that stuff costs a few bucks for a bottle.
