Bayes waterless car wash - Eco responsible car care, at it?s best. Washing your car at home requires up to 150 gallon of water per wash, while contaminated water flows down gutters and storm drains to pollute rivers, lakes and oceans. Our revolutionary one-step wash professionally details the exteriors of any vehicle using only the water in the product itself. Advanced biodegradable polymers encapsulate dirt and lift away debris without scratching the paint. One 16 Oz. bottle averages 4-6 washes, at 20 minutes per wash and no water. You save time, money and the environment.
