Now that most of the nation is basking in warm weather, more people will be out washing their cars. It turns out that there's an environmentally friendly way to get the task done, according to Ford Motor Co.
You might start at the local carwash, the automaker said, a view that's in sync with the Union of Concerned Scientists, a nonprofit advocacy group.
"When you wash your car in the driveway or street, contaminants such as grease and brake dust as well as the detergent itself flow into storm sewers, which discharge directly into our waterways," the group said.
Carwashes, however, drain water into sewers that go to treatment facilities or they filter and reuse it on-site.
But if you are going to wash at home, Ford suggests that you do it on the lawn, so that your grass gets watered as well.
