5 Surfaces You Can Clean With a Pressure Washer (And 3 You Should Never Touch)
Share
A pressure washer is one of the most satisfying tools you can own — but it's not a one-size-fits-all solution. Knowing which surfaces can handle high pressure and which ones can't is the difference between a sparkling clean home and an expensive repair bill. Here's your quick guide.
5 Surfaces That Love Pressure Washing
1. Concrete Driveways & Sidewalks
Concrete is tough and can handle high PSI without issue. Pressure washing removes oil stains, tire marks, mold, and years of grime. Use a surface cleaner attachment for even, streak-free results.
2. Brick & Stone Patios
Brick and natural stone respond well to pressure washing. It removes moss, algae, and dirt from the textured surface. Keep the pressure moderate (1,500–2,000 PSI) to avoid eroding the mortar between bricks.
3. Wooden Decks
Wood can be pressure washed, but with care. Use a lower PSI setting (around 1,200–1,500) and keep the nozzle moving to avoid gouging the wood. Always wash with the grain, not against it.
4. Vinyl Fences
Vinyl is durable and cleans up beautifully with a pressure washer. It's one of the easiest surfaces to work with — a quick pass removes green algae and dirt buildup instantly.
5. Vehicles & Equipment
Cars, trucks, ATVs, and lawn equipment can all be safely pressure washed at low pressure (under 1,200 PSI). Keep the nozzle at least 12 inches away and avoid spraying directly at seals or electronics.
3 Surfaces You Should Never Pressure Wash
1. Asphalt Shingles
High pressure strips the protective granules off shingles, shortening your roof's lifespan significantly. Always use soft washing for roofs.
2. Old or Painted Wood Siding
Older wood siding and painted surfaces can be damaged or stripped by high pressure. Use soft washing with appropriate detergents instead.
3. Windows
Pressure washing windows can crack the glass or force water into the frame, causing interior water damage. Use a gentle hose or window cleaning solution instead.
