I never touch the car. I use a pressure washer (at an angle) and then I use the 'spot free rinse' followed by a brisk drive to 'blow dry'. This avoids water spots and nothing touches that car. Once or twice per year I will wax the car. Been doing this for 20 years and it works the best. I do dry the door jams etc. with a just washed cotton towel when I get home. I have a powerwasher at home but I find it is more trouble that it's worth. I have to buy the detergent and also the spot free rinse agent seperatly and then drag it out to the driveway, hook it up to the hose and eletricity etc. - then the rest of the family wants me to wash their cars.

I have not heard of any car washes recycling water - at least not in the Mid-west. Of course we hardly ever see bans on washing or watering lawns which are common place in other regions.
