How often should I wash my car?
Washing is the process of removing loosely bonded surface contaminants, such as dust, dirt, bug remains and road salt, from the exterior surfaces of your car. Generally speaking, if your car is used as a daily driver, then washing it once a week should be sufficient to enable you to stay on top of the dirt and grime and keep it looking good most of the time. If you choose to wash your car more frequently than this, you should be aware that you run the risk of accumulating sub-surface paint defects more quickly than normal. This is because the vast majority of common sub-surface paint defects such as swirl marks and fine random scratches are inflicted during the wash process, as a result of dirt and grime being moved around over underlying surfaces.
By using appropriate products and techniques this risk can be minimised, but never completely eliminated. Therefore, the frequency at which you wash your car will dictate the frequency at which the bodywork will acquire sub-surface paint defects. We recommend washing your car as little as required to keep it looking good most of the time, and certainly no more than once a week.
