I keep hearing that those brushes they use in the quarter spray bay are a huge no-no. If they're such a no-no, then why would a dealership use the same kind of brush to wash their cars? I work at an Acura dealership in SoCal and we use a soft plastic bristle brush for washing all the new and used cars. I just noticed the past couple of days that the cars that just come off the truck look better than the ones that have been washed on the lot. It looks like there's millions of light scratches on the cars. Using a sponge would take too much time and would kill out backs. What would be a much better alternative? I've already had one customer remark about the "spider webbing".
