I'm curious as to how the rest of you hurdle all the strict water regulations. Although each city and county have their own regulations, ultimately the state does not allow any water runoff from vehicles to enter the storm drain.

I understand there are options such as rinseless and waterless washes, and I have no problem using them. However, sometimes those products just won't cut it with a seriously dirty car. How about engine bay or complete wheel cleaning? I can't see any profitable methods of cleaning your wheels or engine bay without a traditional hose. I also know there are options such as mats you roll the vehicle over so you can trap the nasty water, suck it up, and dispose of it to a safe area later, but seriously, who wants to do that?

As a new detailer trying to get a business going, I'm very interested in hearing what some of you detailers do to navigate these restrictions.
