I work in a rock quarry. Haven't washed my truck in a few months (been working 7 12s). Well my truck is covered in a nice film of clinker/rock dust. My truck is dark blue. Was discussing all this with my boss, who has a dark red truck, and he said spray the whole truck in vinegar and let it sit then spray it off then proceed with washing. It will loosen up the dust.
Thoughts or concerns?
