hello,
I know some about Asphalt roof cleaning but nothing about Shake roof cleaning. I've been reading about EFC38.
1. where do you get it?
2. how do you apply it?
3. how do you neutralize the roof once done and where do you by the neutralizer?
4. also, I have three boxes of 12.5% chlorine in my shop. Can i use this with the right mixture on Asphalt roofs?
please help.
thanks.
