If you want to save a few bucks, skip the car wash and wash your car in your own driveway.
Except if you live in Washington State, that is. There, washing your car in your own driveway is illegal:
Washing your car or boat in the driveway or street is a residential ritual as American as backyard barbecues. But the state of Washington is telling its local governments they must prohibit home car washing unless residents divert the wash water away from storm drains, where they say it causes water pollution.
"I understand this is something people have done for a long time," says Bill Moore, water quality specialist with the Washington state Department of Ecology, which is requiring the ban. "It's not something we should be doing any longer."
He says the soapy runoff is toxic to salmon and other fish and that small metal particles that wash off cars, such as brake dust, is harmful, too.
