A lady i have done some work for sent me a picture of a brick patio that looks awful. I dont have time to go see in person, but its by far worst looking brick ive been asked to clean. I try to stay away from brick but this lady is good customer.
Thinking strong pre-treat and SC then hit with Turbo if needed? I know @Kps0410 had a bad looking patio that turbo worked in… lady said patio hasnt been cleaned in 25 years.
