....I've got a pressure wash and snow foam lance. I find that I get a nice foam, but it doesn't really get dirt off even if I leave it for a while....seems to me if I put the foam on and then use a mit in the traditional way to agitate the foam it would help....will try this out on Thursday......however, was thinking about gatting a brush attachment for the pressure wash? or is this a big no from a scratching point of view...or is there brushes out there which are soft enough to do the job without harming the paint?
