This stuff is brilliant. I have a brick patio which for most of the year is in the shade. It was regularly green with moss but not now. One treatment with this product keeps it moss free for at least a year. No more pressure washing!

Product FAQs

Q: Hi I am looking at purchasing a The BigBOY 2 Backpack - 22L to clean my roof. my questions are can this product b used with it and is this product safe for use on and around solar panels?

Christopher Thomas

A: Yes, it can be used around solar panels, but we would recommend keeping any over spray to a minimum.

Response from Jacob

Q: I asked in an earlier question, is your product tested on animals. I appetite is safe for animals post application, but is it tested on animals


A: We use a chemical called BAC50 within our formulation which is widely used Biocide. We buy this ingredient from a 3rd party company and then blend the product. We certainly do not test any of our products on animals. After application and dry, it becomes inert and safe for animals. Hope that helps.

Response from Aaron

Q: Is your product tested on animals? And I'd like to use on external windowsill made of stone but don't want it to drip on to the ground beneath. Can I apply with sponge? And will it harm metal fence on a stone wall


A: The product will not damage any external hard surface. It is safe for animals and wildlife once dry. Hope that helps.
