Patio Black Spot Remover Artificial Stone 2L

Refresh your outdoor surfaces with Patio Black Spot Remover for Artificial Stone — a specialist artificial stone patio cleaner formulated to remove black spots, stains, algae and grime from manufactured, man-made and precast paving surfaces.

Ideal for manufactured slabs including Marshalls, Bradstone, Haddonstone and other precast patio slabs, this powerful paving slab cleaner also works on concrete, porcelain, resin driveways and composite decking. Its deep-cleaning formula penetrates the surface to break down stubborn black stains, organic staining and discolouration, helping restore the original colour.

Patio Black Spot Remover for paving slabs also removes common outdoor stains, including bird droppings and berry staining, making it an effective patio cleaner for everyday garden maintenance.

Unlike harsh jet washing, which can damage paving surfaces and loosen pointing, this patio black spot remover gently lifts dirt, black lichen, algae and grime while helping restore colour. It makes follow-up pressure washing easier and less abrasive, giving longer-lasting protection and beautifully refreshed garden paving.

For year-round patio protection, follow up with our Patio Black Spot Preventer. Applied annually, this spray-and-leave patio treatment helps prevent staining and discolouration, reduces the need for regular power washing, and removes green algae within 5 days of application. Use it 12 months after the initial black spot removal treatment to help keep paving slabs, concrete and artificial stone surfaces looking cleaner for longer.

Works deep into the surface to revive the original colour and texture of your stone.

Safe for gardens, the biodegradable, acid-free formula can be rinsed into flower beds and lawns without harming plants or grass, making it a practical choice for effective patio cleaning around outdoor living areas.

Patio Black Spot Remover is safe to use around pets. As a precaution, keep pets away from the treated area during application. Once the remover has been washed off the surface, the patio, paving or driveway is safe for pets to walk on.
