Hi,

I watched your video on cleaning moss from the roof of asphalt shingles.

and it looked like it did a very good job.

I have the same problem and I wanted to try the solution that you sprayed on.

The pool supply in my area does have liquid chlorine- 12% sodium hypochlorite by the gallon or 4 gallons.  I’m trying to determine how much I need.

My question is- do I apply it straight or diluted with water?

Thanks,

Richard
