Question and Answer

Indian stone
Is this product suitable to use on Indian stone which has Lichen, Algae and black spots marks all over it?
Answered by Longacres 09/02/18

On Indian stone (which should be a natural product) you should use Patio Black Spot Remover for Natural Stone.

It says above not to use on block pavers. Why is this? Is there anything I can use to remove black spot on block paving? Thanks

Natural stone. Is product suitable for use alongside a pond with fish?
