FohmerToo spraying 4% copper sulfate roof cleaner

[sorka]

I use copper sulfate on my roof too but it is deadly to plants if the over-spray hits the lawn or shrubs. Ask me how I know :)

Can you please do a video where you can clearly see a LOT of algae on the siding of a house to see how well this work? From what I've been watching most of your videos are on fairly clean areas and it is hard to see just how well it cleans.

Try the bleaching solution full strength and you will see why they tell you to use it. I had a bottle of bleach tip on my bench- you get to see how to make paper fiber really quickly

Bur sir my shingles packs says to use sodium hypoclorite for cleaning stained roofs.
