Concentrated Black Spot Remover
Target stubborn lichen and organic staining with Brook & Bramble Concentrated Black Spot Remover — a specialist treatment designed to break down deep-set black spots that standard patio cleaners leave behind.
This powerful, chlorine-based solution penetrates porous surfaces like natural stone, block paving, and concrete to dissolve the root structure of black lichen and other persistent biological growths. Perfect for spot-treating patios, driveways, paths, and walls where embedded marks spoil the surface.
