Waterless car wash

One of our Cool Tools readers, Jon Bonesteel, recommended Rain-X Waterless car wash. He wrote, “This stuff is magic! It saves a LOT of water and washes a car better than soap and water. The resulting finish beads water like wax and it’s so easy. I was skeptical, but I will never wash a car with water again.” I decided to try it myself and I agree with him. It’s easy to use and my car is shinier than it’s ever been. — MF
