I wash my vehicle at home, and the finish looks dull and marked up. What is causing this?
Washing your car at home can be harmful to the finish. Studies conducted by the University of Texas show that a single home wash by hand can leave scratches in the finish as deep as a tenth of the paint’s total thickness. Additionally, the average garden hose cannot supply enough water or water pressure in combination with detergent to avoid damaging the car’s finish. The UT study concluded that auto owners should refrain from home washing as only professional washes supply correct levels of water and water pressure in conjunction with gentle yet powerful cleaning agents to safely and effectively clean vehicles without compromising the finish.
