About Pressure Washers for Fencing
Use 120–140 bar at a fan or 25° nozzle. Avoid turbo nozzles which fur softwood grain. Work top-down, with overlapping strokes, 20–30 cm from the panel.
Top picks: Kärcher K4 Power Control (with Wood mode), Nilfisk Core 125, Bosch UniversalAquatak 135. For very large boundaries, a petrol Hyundai HYW3100P pays back fast.
Pre-treat green panels with a fence cleaner (Cuprinol Decking & Fence Cleaner) for fastest results. Re-treat with a stain after the wood dries fully (48+ hours).
