Whether you live in a drought-prone area or not, dumping buckets of water to clean the car seems a little extravagant. How extravagant, you wonder? With most garden hoses spraying about 10 gallons of water per minute, the average driveway wash uses 80 to 140 gallons of water. That’s a lot, actually—and in places now forced to restrict usage so there will be water to drink at summer’s end, it probably wouldn’t be allowed.
Fortunately, you can give the car a good scrubbing using less water than it takes to brush your teeth. Spray on a waterless car wash, which breaks down grime and can be wiped off without a rinse. Eco Touch's Waterless Car Wash uses just 4 to 6 ounces of water per wash and polishes as it cleans (www.ecotouch.net). Lucky Earth's Waterless Car Wash (www.luckyearth.com) will give you seven to ten washes per bottle.
