A Brazilian company, DryWash, uses a native Brazilian wax to clean cars spotless without the use of water. The company’s method has saved millions of gallons of water, and its impressive sales have encouraged the company to expand overseas and into other services, including a waterless washing service for airplanes and helicopters. The Company generated $2.7 million in revenue in 2005.
