About Pressure Washers for Caravan Cleaning
Stick to 100–130 bar with a fan lance. Avoid turbo nozzles near windows, seals, vents and decals — they'll force water past seals and lift graphics.
Best caravan picks: Kärcher K4 with extension lance, Nilfisk Core 130 and the Bosch Fontus battery washer for campsite use where mains isn't available.
Pair with a caravan-safe shampoo (Fenwick's Caravan Cleaner) and a soft brush for the roof — the most-neglected and dirtiest part of any caravan.
