Has anyone had any success soft washing grease stains from concrete surfaces and if so what did you find worked best to remove those grease stains? I have been hired to clean a hotel's roof and they inquired about having their concrete walks cleaned as well. However their concrete walkways have oil and grease stains in addition to organic stains and I am trying to avoid using any pressure washing equipment if possible. Any suggestions or opinions would be appreciated. Thanks in advance!
I have a customer whose HOA told her to either clean or replace her driveway because of the extensive oil stains on it. Will these products work on driveway pavers, too?
Your not always going to get them 100% Depends on permeation of the oil and the cleaner. Craig's site has info on this in Barq 9 instructions. Some stains can be inches deep.
