About Pressure Washers for Moss Removal
Aim for 130+ bar at 8 L/min minimum. Pair with a surface-cleaner attachment for flat areas (driveways, patios) and a fan or turbo lance for vertical walls and steps.
Pre-treat with a biocide moss killer (Patio Magic, Wet & Forget) 24 hours before washing — this lifts roots and prevents fast regrowth.
After cleaning, re-sand block paving joints with kiln-dried sand. Without re-sanding, moss returns within months and slabs start to rock.
