Doug Dahlke 114 Report post Posted May 10, 2007 I washed a new house yesterday that had the softest concrete I have seen. I usually use a hydrochloric acid cleaner to handle the red clay here and an adjustable pressure wand. I used the cleaner on the rear concrete patio and a low pressure rinse but even at low pressure I could see some cream moving. Did the rest of the house with no chems and low pressure. This house had a large concrete entrance patio with a brick front. Of course there is mortar all over the concrete. Not big globs but more like a thin film that is spread all over it. It was still wet when I left so I couldn't see the finished look. I don't know how to get the mortar off without damaging the concrete. Acid will melt the mortar but it will also soften the cream. About 50 cents worth of plastic would have solved the problem but I have done enough of these now to know that won't happen. It is amazing what a mess these guys make of a house.
