Below are a few different demos we did at a sports arena. You'll see before and after shots of that prevalent well water rust stains holding on the outside pillars, which obviously is no match for Official Orange. As well as other before and after shots showing rust and heavy soil build up!! All demos were done with a 10-1 mix,we always recommend trying the product light before hitting it with the strong!
