Few people realize that washing our cars in our driveways is one of the most environmentally
un-friendly chores we can do around the house.

Unlike household waste water that enters sewers or septic systems and undergoes treatment before it is discharged into the environment,
what runs off from your car goes right into storm drains - and eventually into rivers, streams, creeks and wetlands where it poisons aquatic life and wreaks other ecosystem havoc.

The International Carwash Association
reports
that washing a car at home typically uses between 80 and 140 gallons of water
and commercial car uses between 40 and 60 gallons per car !
