Did you know that a typical home car wash uses between 80 and 140 gallons of water? This summer, put down that water- (and money-) wasting hose, and pick up a bottle of Lucky Earth "Waterless" Car Wash instead. Made with organic soaps and free of the toxins found in traditional car-wash detergents, this environmentally safe solution can be used on all solid surfaces, including paint, glass, fiberglass, plastic and chrome. But the earth isn't the only one that's lucky. With each 32-oz spray bottle ($16.99) good for 7 to 10 washes, your wallet is, too. Hey, you're already spending plenty just to fill your car—why should you pay a fortune to clean it?
