New Clean 60 Patio Cleaner has, amongst other compounds, an active biocide – this destroys organic vegetation such as weeds and moss between slabs or pavers. When you apply New Clean 60 to patios or pathways next to grass or similar vegetation, you must ensure you thoroughly wash away the cleaner at the end of the process.

Dowsing lawn and other areas with clean fresh water will dilute away the remaining cleaner and whilst it may temporarily lighten the grass, it will regain it’s natural colour shortly afterwards.
