Patio Black Spot Remover is currently the only product developed specifically to safely remove those hideous black spots and restore the natural colour to garden stonework. Patio Black Spot Remover for Artificial Stone will remove black lichen from all types of artificial surfaces, including green algae and white fungi. Using Patio Black Spot Remover will help maintain the life of your garden stonework including your pointing. When you rely on pressure to clean your stonework, you risk removing the surface of the stone whilst helping to dislodge the pointing.

Patio Black Spot Remover gently restores the natural colours and lifts dirt and grime effortlessly making pressure washing effortless. To maintain your garden stonework and stop the return of black spots, buy and apply our Patio Black Spot Preventer annually. This will remove any black spot spores before they have the chance to germinate and turn into spots. It will also remove green algae without the need to power wash! The Preventer does not need to be applied until 12 months after the Removal process.

Patio Black Spot Remover is biodegradable and acid-free allowing you to wash the product into the flower beds and over the lawn without causing any harm.
