Need to wash your car after it rains?
Washing your car is actually not as easy as it seems. Doing it wrong can damage your paint. If you don't do that, your car could rust sooner than expected. Fortunately, it's easier to tell when your car needs a wash than whether your clutch or brakes need to be replaced. But cleaning your car is more than just soap and water. That's why, although it may seem counterintuitive, rain alone won't clean your car.
