I have started to clean this with wfp but leaving green shadows where it's not all coming off what is best to get this off?

Hypo, but no-one on here uses it.

Do your research and make your own mind up.

Big old job that one...good luck as will be a mare to do from the ground using chems especially on those chimney stacks.

Use ya tank that ya wfp out of, so u just have the tank - pump - hose reel - pole hose, so it's not going through any di bottles or anything.

I have done this so no it will work, I add a full barrell 20L, to a 650 tank to start off with if u find it's not killing the moss off for u just add more to ya tank til u happy.

Once u done with treating it all, u then just wash it down with water, I would have a hose running into the tank as am working, and u will have to allow a few tanks of water to run through it before going back to wfp.
