I would use the following mix INSTEAD of the sauce or cider.
Use 35 percent Sodium Hypochlorite, 60 percent water, with a caustic overide of 10 percent Sodium Hydroxide.
So, for 100 gallons total mix, we need 35 gallons chlorine, 60 gallons water, and 5 gallons liquid Sodium Hydroxide 15 percent.
Sometimes, Sodium Hydroxide comes as 50 percent, so be careful.
IF it comes as 50 percent, do NOT add 5 gallons.
Dilute 1 gallon of 50 percent Hydroxide in 4 galons of water, and add THAT.
Sometimes, the saponification of Hydroxide is necessary on heavy organic deposits, like this roof presents.
You will alos benefit greatly by adding a little surfactant that is high PH compatable.'
This will aid you with better dwell time on a steep roof like this.
sauce/cider? Need help to clean this roof!
