Will 3-4 percentage of SH destroy any vegetation? How can I avoid that from happening I don’t want to go around ruining ppl’s stuff, ty

Yep…sure will. Don’t need that high % to clean unless your cleaning a roof.

Ppl say 3-4% on concrete or brick, that’s why I’m asking

You need more time reading the answer like this are all over the place in here. Look up and see the search bar. How to clean concrete.

Well, there are times when 3% comes in handy, mainly moss and lichens especially. I guess it depends what part of the country (world?) you are located.

i’ve used pure sh on lichen on rocks, it laughed and me and said what else you got?
