I know it depends on what the surface looks like (what type of prep needs to be done) but what is your go to solution that helps you power wash your exteriors?
Are you talking about a housewash for cleaning or a housewash for prepping for a repaint??
Simple Cherry does not have any TSP. It is the TSP Substitute (TPP) and it is not as harsh if at all. It also has enough buffers where TSP is straight juice.Ya got to where unless I was personally there I don't add any F-13 to the regular mix. Had a deal last summer where some windows got a bit etched.....(rinse rinse rinse). I can honestly say I'm not sure how much TSP if any is in simple cherry. I know TSP has more of an "etching" quality (seems to me anyway).
