This may be a dumb question since I have only been cleaning roofs with pressure since getting into the business but what is the average mixing ratio of this sodium hypochlorite. Are you mixing it with water? This is a salt based chemical right? How long are you leaving it on before rinsing?
I am fairly new to this board also (roughly a month) Everything that you could possibly want to know is here, these guys are great. I will tell you that if you use the search icon at the top of the page, you can look for the answer to your question.
Best of luck with your business.
