Roofers, DIY'ers best product for lichen removal

dibble35, Oct 1, 10:09pm
Just having my roof replaced and went up to have a look at the part they have finished. Noticed how bad my gutters were, lots of lichen on the inside. What is the easiest product to apply from the ground, Im a bit afraid of heights, especially when there isnt any scaffolding there, couldnt bring myself to go anywhere near the edge, so is there a product i can spray onto the roof that will then go into the gutters and kill the lichen? (and not damage the finish to the roof - colorsteel) TIA

I have used one of the 30 seconds products, or its competitor. It worked.

I searched lichen removal and only came up with one.
This one.
What should I search to find these threads?

Search `lichen' but for the past year.

forget the fools and go to bunnings and pay about $20 for a 2 liter bottle of pool winteriser - green in colour - with 250 gms per liter benzelkonium chloride - use 300 mls per 10 liters water and you have the best and cheapest wet and forget to spray any surface around the home, particularly the spouting!

Don't get it on the outside of the gutter if it is coloursteel. It will leave a mark.
(We do it commercially)
