It matters how and where you take care of your car. When you are working on your car, take care to catch your used fluids in safe containers that you can take to a recycling center. Never dispose of these chemicals down a storm drain. If you spill anything, mop it up quickly. It's best to take your car to a professional car wash. They have special equipment to treat all the dirty water they produce. If you wash your car at home, it's best to park your car on the grass, first, rather than leave it on the driveway.
