'GREEN CLEAR' PRO Kills & Inhibits All Organic Growth
Product Reviews
By Ian CunninghamFROM Welwyn

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!

By Donald Johnston

Great stuff , things looking darker now

By Chris Shorter

We have used this product on our club tennis courts and it seems very effective in killing the moss after about a week- though one needs to be careful not to use it when rain is expected in the next few hours as that reduces its effectiveness. I would certainly recommend the product.
