i have gotten into the roof cleaning the past few months and i am just wondering. when you mix dawn soap or tsp with the bleach it just acts the same basically foaming and showing where you have already been with the chemical and letting it sit on the surface for a min and work its magic. please comment and help me out guys i just want to do the best job i can for customers. Oh and if there is something else i can put in the mix to try and overcome some of the bleach smell PLEASE let me know
