I will probably give it a try. Doesn't look too abrasive. See a company in Edmonton has it. Wish I had a shop to do it in. Can't really pressure wash in the garage. Does it come off the cement if I do it on the driveway. Or will it leave purple stains.
My driveway is all funny colors so never noticed but it just rinses off the truck when used so I am presuming it does the same on cement. I would put some in a corner direct, let it sit, then rinse it, see how it reacts on Cement.
