How would one go about washing a painted wood plank sided house? I was thinking just a weak hw mix but want to make sure before moving forward. The paint looks like it is in good shape but I have told the home owner there may be some flaking.
We wash painted wood plank a fair amount. I check for oxidation so I know how I want my mix, always pre-wet any painted surface, and soap from the bottom up. Give her a thorough low pressure rinse and never had a problem.
