| hesitant... Just because I live in Southern California and our rain is far from pure, I'd steer clear of using rain water to wash your car. Maybe watering plants is okay, but not the car.
If your concern is to save water, for most washes try a "waterless" car wash like QEW or Spray & Wipe. If a car is filthy, not much can beat a hose and running water. But in between washes are fine with the above. A lot of mobile detailers use these products to avoid having to carry around GALLONS of water in their rigs and to comply with local water reclaimation laws. |
