Review on Rain X 620034 6PK Spot Free Wash by Jake Jones

Remove stains without washing? If that sounds too good to be true, it is. I followed the instructions exactly, but still had to wash and dry it again. The claim that it doesn't stain, at least here where the water is hard, is nonsense. Contacted them to see if there is a problem. Your Answer? This product may not work properly if you have recently applied wax or any other protective coating to your vehicle. It won't damage the finish, but it won't "stain free". For vehicles that have recently been waxed or coated with a protectant, the manual states: Changed to one star based on manufacturer response. it goes back Pros: - Inexpensive - Removes dirt well - Nice color Cons: - Leaves stains.
