Patio Black Spot Remover for Artificial Stone is designed to remove stubborn black staining from manufactured and man made outdoor surfaces while restoring their original colour and finish. The specialist formula works deep within the surface to break down discolouration without damaging paving or surrounding areas.
Suitable for manufactured paving slabs such as Marshalls, Bradstone, Haddonstone and precast stone, it is also effective on concrete, porcelain paving, resin driveways and composite decking. The biodegradable, acid free formula gently lifts dirt, bird droppings and berry staining and is safe to rinse into lawns and flower beds. Safe for pets once washed off, this 2L size is ideal for smaller areas or targeted treatments.
