If you want your car to last longer, you have to wash it. Especially if you live in an area where salt is used on the roads in winter. This road salt can quickly rust out the body of your car. Also, if you live in an area with hard rain water, you want to wash and wax it regularly. If you live in an area with a lot of sun, you want to make sure that you wax your car regularly. All of these different elements can reek havoc on your car's body and on your paint job. Taking care of your property is a sure way to increase the life of the item and your car is no exception.
