Been using simple cherry but will be giving the roof snot a try next if the price is not too much higher.
Roof Snot is WAY cheaper than Simple Cherry if you do the math. I think 10 pounds of Simple Cherry is about $35 and makes about 20 fivers of house wash mix. That's $1.75 per bucket of mix. Roof Snot is about $80 for 5 gallons, whitch makes 213 fivers at 3oz per bucket. That's $0.32 per bucket of mix. And it is PH neutral, which means it can mix with pretty much anything. It's also pretty much essential if you clean roofs without gutters. Roof Snot is always old to have on your truck.
