Transform your patio with our Patio Black Spot Remover for Natural Stone – the only solution developed specifically to tackle stubborn black stains, helping break down discolouration while restoring the natural beauty of your garden stonework. Patio Black Spot Remover can be used on Indian Sandstone, York Stone, Limestone, Travertine (including Portland and Bath Stone), and all other types of natural stone. This powerful treatment removes stubborn black staining from patios. It works deep into the surface to revive the original colour and texture of your stone, leaving your patio looking fresh and renewed after pressure washing. Available in two sizes: 4 Litres – treats up to 20m² 2 Litres – treats up to 10m² Unlike aggressive pressure washing, which can damage the stone surface and dislodge pointing, our patio black spot remover for natural stone gently lifts dirt and grime, making any follow-up cleaning effortless. It helps prolong the life of your stonework while delivering results that standard patio cleaners cannot match. To keep your stone looking its best year after year, follow up with our Patio Black Spot Preventer. Applied annually, it will prevent staining and discolouration and remove green algae within days without the need for power washing. The Preventer should be applied 12 months after the initial removal process. Safe, biodegradable, and acid-free, our formula can be rinsed into flower beds or lawns without harming plants, making it both effective and environmentally responsible. Patio Black Spot Remover is safe to use around pets. As a precaution, we recommend keeping pets off the area whilst applying the product. Once the Remover has been washed off the surface, it’s instantly safe for pets to walk on the area. Coverage Tip: The coverage rate is based on a patio around 3 years old. Older or heavily stained stone may require additional treatments. Always test on a trial slab first to gauge results for your surface.
