Hey guys, want to do some RCIA Research and advance the roof cleaning art, possibly ?

This is TSP, our old friend, but with a difference, it is chlorinated

It is fairly cheap too TSP with Chlorine already added

This might be "Da Shit"

I am soo very busy, out cleaning roofs in 95 degree heat, and running this forum, selling jobs, just too much on my plate right now. If anyone would like to help, it will be appreciated.

It does say it leaves a residue, so it is probably calcium hypochlorite with TSP, still it might be interesting to see how MUCH, if any, a small amount of it leaves when used as a roof cleaning additive. It COULD be that if a very small resudue is left that can barely be seen, it will Protect the roof from algae re growth.
