Patio Black Spot Remover for Natural Stone is specially developed to tackle stubborn black staining on outdoor stone surfaces. Designed to work deep into the stone, it breaks down discolouration and restores the original colour and texture of patios, paths and paved areas without the harsh effects of aggressive pressure washing.
Suitable for Indian sandstone, York stone, limestone, travertine including Portland and Bath stone and other natural stone types, this powerful yet gentle treatment helps prolong the life of your stonework. Safe, biodegradable and acid free, it can be rinsed into lawns or flower beds without harming plants. It is also safe to use around pets once washed off, making it ideal for family gardens.
