About Pressure Washers for Outdoor Tiles
For porcelain and ceramic, 130–160 bar with a fan lance or surface cleaner is ideal. For natural stone (limestone, travertine), drop to 100–125 bar and use a wide fan only.
Top picks: Kärcher K5 Premium, Nilfisk Core 140, Bosch UniversalAquatak 135. Combine with a tile-safe cleaner like HG Outdoor Tile Cleaner.
Don't blast directly at grout lines — they'll erode under sustained high pressure. Work parallel to the joints and keep moving.
