Oh and don't I know this is going to stir up a hornests nest, but I'm just sayin, one of the car wash booths work good for this and they have to treat the water before it goes into the waste stream to avoid the minimum $10,000 fine. (I know this because I used to work at a place that somehow couldn't see fit to treat their waste water correctly and collected several of these fines) It isn't very responsible, when there is such a readily available (and cheap) alternative available. But in all fairness, some of the car wash places don't want you doing this in their place, but many don't mind. YOU may not care, but your children probably will.
