About Pressure Washers for Conservatories
Use 100–125 bar maximum on polycarbonate, glass and uPVC. Pair with a 7m+ telescopic lance (Karcher TLA 7) to reach roof panels safely from ground level.
Top picks: Kärcher K3 with telescopic lance, Nilfisk Core 125 and Bosch UniversalAquatak 135. For soft-wash chemistry, use Wet & Forget Outdoor as a pre-treat.
Always pre-wet seals and silicone joints, and never aim at vent ridges — water can be driven into the eaves.
