What Is Pressure Washing?
Pressure Washing is a surface-cleaning method that directs pressurized water at dirt, algae, mildew, and loose material. The water stream removes buildup from wood, concrete, siding, and other surfaces. On a fence, pressure washing prepares the wood by clearing surface grime before staining, while preserving sound fibers when handled with care.

Key Takeaways About Pressure Washing
- Water pressure removes buildup from a surface.
- Wood needs controlled pressure to avoid fiber damage.
- Pressure washing does not replace stain or paint.
How Pressure Washing Works
Pressure washing sends water through a narrow nozzle to create a focused cleaning stream. The operator controls the pressure, spray pattern, and distance from the surface. These choices affect how much dirt comes away and how the material responds.

For a fence staining project, pressure washing removes soil, algae, mildew, and loose old stain. The operator works with the wood grain and watches for raised fibers or soft spots. The fence must dry before stain goes on, because trapped moisture can affect the finish.
Pressure Washing and Fence Staining
Pressure washing is surface preparation, not a protective coating. Stain adds color and helps shield exposed wood after the cleaned surface is ready.
From the PainterSammamishwa.com team
When we prepare a fence for staining, we check the wood before washing it. We adjust the spray so the stream removes buildup without cutting into sound fibers. After washing, we look for loose material and allow the surface to dry before applying stain.
Pressure Washing in Practice: A Real-World Example
A weathered fence may have dirt, algae, and loose stain on its boards. We pressure wash the surface with controlled settings, then prepare the dry wood for a new stain coat.
