Sewer vs. storm drain - how washing you car by hand is bad for the environment. Water used to wash your car at home or at a charity wash drains directly into and poisons the environment. At Liberty Car Wash, the water we use flows to the sewer for treatment and processing before being released into the environment. Even if you use a environmentally friendly soap like we do, your wastewater may carry trace amount of metals (copper from brake dust and zinc from tire wear) along with small amounts of gasoline and diesel fuel, oil, grease and antifreeze. When combined with the fact that a professional car wash uses only a fraction of the water used to wash a car by hand, it’s no wonder that The Nature Conservancy and other organizations recommend washing at a professional car wash as the more environmentally friendly choice.
