Moss-covered stones on the patio, not a pretty sight. I was very curious to see how this Moss Remover would act. The mixture was diluted as indicated and then sprayed. After several hours, the effect was seen, the stones looked back as they should look. Only the spray bottle made me trouble because you much strength must expend that I have not. A pump spray bottle managed Remedy.
The product I can only recommend, although caution is advised.
