Is washing my car damaging to my paint?
As long as you take the following precautions, it most certainly should not:
-do not wash the car in direct sunlight
-use soap designed specifically for washing cars (avoid dish soap, hand soap, etc.)
-if the sponge, towel or other item you are using to wash or dry the car falls on the ground, hose it off thoroughly or set it aside and find another clean one; dirt and other contaminents get picked up by the item and can scratch the paint or the glass if you rub the item on the car’s surface
