Patio Black Spot Remover is currently the only product developed specifically to remove those hideous black spots and restore the colour of your stonework. Patio Black Spot Remover for Artificial Stone will remove black spots from garden ornaments and all pre cast patio slabs including Marshalls, Bradstone, Haddonstone and other cementitious based slabs.
To maintain your garden stonework and stop the return of the black spots, buy and apply our Patio Black Spot Preventer annually. This will kill any black spot spores before they have the chance to germinate and turn into spots and will also remove green algae without the need to power wash!
