I have a 125 Gal. tank, what would be a good mixture for shingle roof cleaning in Pittsburgh? How may 14 sq. roofs can be cleaned with this amount? Also, will the mixture be good for the next day? Thanks for your help.
All the answers to these questions can be found in the search function, but me being the good guy that I am, I will help you. As a newbie, you will use more solution than somebody with experience. Most will use between 30-40 gals of solution per roof. You will probably use 50-60 gals. The solution may be good the next day, depending on what surfactant you use and/or if you add alcohol. See "apple sauce" in the search function for the mixture. Hope this helps!! You're welcome! Gary
