Avoid Pressure Washers & Car Wash Services Prevents Paint Peel.
When I was a young electrical electronics controls service engineer for a nationalised water board, we had nearly new white vans & customer facing, were expected to keep them clean & presentable.
With youthful over exuberance, I used the companies on site car wash pressure washers weekly & eventually noticed a strip of topcoat peel off under the pressure wash so called cleaning water jet on the six month old van.
I never used a pressure washer again on any vehicle in the last 40 years.
