hey guys, i'm having a problem finding a chemical to use in car washing, we do a couple of auto auctions and its taking us too long to get the jod accomplish. I've heard of guys around my area using some type of touchless chemical to wash limos with out touching them just spraying soap and rinsing off with DI water. i do two steping in trucks but i wouldn't spray acid on a $ 90,000 vehicle. any suggestions ?
