I used it. Once. But not too strong.

Even WITH 500psi, the roof didn't come clean. I gave up and used chlorine on the last 1/2 of it. That experience sold me forever on chlorine for roofs...I spent about 2 hours fighting with the hydroxide and the pressure hose, getting less than 1/2 the roof done...spent the last hour finishing the last 1/2 or so, including cleaning up and driving off. That was with the Xjet.
