99% of my roof cleaning jobs are cedar. Every so often I get a request from a realtor to clean a roof for a client that is not cedar. I did this job Friday 07-26-2013 that was asphalt and I had to go back to the SH, which has been along time for me. So I use my normal mix and added 16ozs of Lemon Aid to 110 gallons of mix, I made a big batch cause I do have a couple small jobs to knock out also. So the home owner Kelly comes out while I am spraying and tells Maria my ground person that she can smell lemon and that it smells nice and clean. Now I tried the apple back in the day and it didn't work well. This Lemon Aid works great and thank you Russ from Southside, I am glad I bought 10 gallons at the Des Moines Show.
