Newbie here. This forum is great and has answered many of my questions. However, I have 2 questions: 1. Baking Soda. I read through most of the forums and can't find anything on baking soda. Does anybody use baking soda? If not, why not? I am looking to come up with an Eco-Friendly option as we work in Portland and it's a big deal. I tested a small spot on my own roof and it killed the moss quite well (1 cup baking soda to 1 gallon water). Mostly looking to kill moss and algae prior to a hand cleaning. 2. Dye- Does anybody have any suggestions on dye that can be added to mixtures that isn't permanent? I was thinking a green dye to promote "Green" roof cleaning practices. Thanks in advance!

That's funny! There are actually some Karvonen's here locally in Vancouver. I may reach out to you as we develop our methods.

Yes, i'm told it is. Don't know much about Finland though.... :-)
