A few cities in California are asking non-profit groups to use waterless car wash products, instead of the old fashioned bucket of water and a sponge. Why? Because many municipalities are trying to find additional ways to save water and prevent storm drain pollution, which leads to the environment.
In Santa Monica there is a big push to do this by the city, yet amazingly enough the Santa Monica Bay is polluted because the sewer treatment plant overflows about twice per year. Worse, surfers are warned not to go in and no one dares eat the fish. But this has nothing to do with car wash fundraisers.
Well we must all realize that Dry Wash-n-Guard Waterless Carwash is sold as a Multi-Level Marketing Product right? It is very expensive per bottle. It takes 15 minutes to do a car with it as opposed to 5-minutes with a pressure washer. So the kids groups doing the "apple pie" traditional car wash fundraisers cannot possibly make the money they need using it.
In one online book adopted by the Storm Water Control district for the City of Los Angeles, you will find accepted BMPs or best management practices approved by the RWQD Regional Water Quality Control District, which fully comply with 13.262 of the California Water Code.

It is unfortunate that we attack non-profit groups with environmental laws and rules, which really do not apply, after all the Federal Clean Water Act of 1972 was for things like oil spills and strip-mining, not fundraiser car washes.
