After first purchasing a vehicle, owners commonly regularly wash the exterior to keep it looking fresh and shiny. But, after a while, the enthusiasm wanes. Yet, there are many reasons why routine washing is a must. The frequency of washing depends on the geographical location and the degree of exposure the car, SUV or truck has with the environment. If driven daily and stored outdoors, the vehicle needs more frequent washing.
Routinely washing the vehicle's exterior ensures the longevity of the inner working parts along with keeping the vehicle's optimal appearance. When continually exposed to dirt, grit, tree sap and bugs without regular washing, the protective coating becomes damaged, which encourages rust.
Research indicates that clean vehicles have a 10 percent greater fuel efficiency. The debris that remains on dirty vehicles contributes to drag, which puts more stress on the powertrain. Keeping the vehicle clean inside and out also ensures the health of all occupants.
