How often should I wash & wax my car?

We suggest you wash your car at least once a month with an auto wash liquid soap. In the winter pay close attention to remove winter salt deposits from underneath your car. Sometimes car owners forget to rinse off dirt before washing; any dirt rubbed into a car's paint surface can cause scratches. We also suggest that you run a wash mitt or rag along the inside bottom edges of your car's doors, hood, trunk or hatch as these areas commonly trap moisture and dirt and can cause premature rusting. We suggest that you do not use household detergents because they can be harsh and can remove the wax finish on your car. A nice chamois does a better job of drying a car than a towel does does because of its absorbency abilities. A bath towel can be abrasive. If you don't want to use a chamois to dry your car then ask for nonabrasive towel used to dry a car when you visit the auto repair store.

Giving your car a good wax job will protect the car's body from filthy winter roads. Waxing in the spring is also a great idea. Never wax your car in direct sunlight as this can cause chemicals in the wax to damage your automobile's finish. Newer cars have an invisible coat that protects the paint. Some people think the clear coat lets them avoid waxing. But road gunk and the elements wear down the very coat that wax protects.
