�� If there are no storm water management controls in place , choose a site where the wash water can soak into grass , gravel , or be diverted to nearby landscaping . This will allow the wash water to filter through the vegetation and / or soil instead of flowing directly into a storm drain . Absorbent pads , which can be purchased at automotive shops , can also be placed in the curb or grass swale to catch oils and other chemicals .
�� Remove all trash and debris from the car washing area . �� Do not use acid-based wheel cleaners or engine degreasers .
�� A soap-free wash is best for the environment . If you do use soaps , use cleaners or detergents labeled “ non-toxic ,” “ chlorine-free ”, “ phosphate- free ,” or “ biodegradable .” The safest products for the environment are vegetable or citrus-based products . Using biodegradable soap does not lessen its immediate environmental impact – it simply means that the soap will degrade in time . A flush of “ biodegradable ” soap suds will still harm fish or invertebrates in your local stream .
�� Use a bucket of soapy water to re-soap rags or sponges throughout the wash rather than adding soap directly to rags or sponges .
� Wring sponges and washrags into buckets , not the ground .
� Conserve water by using a spray nozzle with an automatic shut-off .
� Always empty buckets into the sanitary sewer system ( e . g . sinks or toilets ), NOT down the storm drain .
Remember to clean up after the car wash fundraiser . Have a volunteer walk the perimeter of the site to pick up trash and debris and dispose of it properly .
Remember to stop and think before you allow anything to go directly into the gutter or storm drain .
STORMWATER FACT : Both the owner / occupant of the property on which you conduct your car wash and your organization are responsible for implementing pollution prevention measures . Ensuring that your group implements these practices will protect the site owner / occupant and should make them supportive of hosting car wash events of the future .
