Queen Clean Report post Posted April 15, 2018 Hi Im new here and researching what I need to get started in softwash roof cleaning. I have over 30 yrs doing high pressure cleaning and wanted to add options to my cleaning business. My first question is ..SH means Sodium Hypochlorite or does it mean Sodium Hydroxide ? 2 Apple Roof Cleaning (813) 655-8777 and Tim-in-Indy reacted to this Share this post Link to post Share on other sites
