Unlike harsh jet washing, which risks damaging the surface or dislodging pointing, our patio black spot remover for paving slabs gently lifts dirt and restores colour, making any follow-up cleaning with a pressure washer far more effective and less abrasive. The result is longer-lasting protection and beautifully refreshed stonework.

For year-round results, follow up with our Patio Black Spot Preventer. Applied annually, it helps maintain a spotless finish. Preventing staining and discolouration without the need for endless power washing. The Preventer should be applied 12 months after the initial removal treatment.
