Fence Power Washing & Cleaning

A gray, mildew-covered fence isn't just ugly — stain or sealer applied over dirt will peel within a season. Power washing removes every layer of grime, mold, and gray oxidation so your finish bonds properly and lasts.

The Right Pressure Matters

Too little pressure leaves mildew behind. Too much damages wood fibers and raises the grain, making the fence look fuzzy. Here's the safe range for wood fences:

PSI RangeBest ForSafe for Wood?
500–800 PSILight rinse, delicate surfaces Yes
1,000–1,500 PSIStandard fence cleaning — removes dirt & mildew Yes
1,500–2,000 PSIHeavy stains, gray weathering, paint prep Yes
2,000–2,500 PSIRisk of fuzzing/scarring wood grain — avoid No
2,500+ PSIDamages wood fibers — never use on fences No

Our Cleaning Process

1

Apply Wood Cleaner or Mildewcide

Spray a diluted oxygen bleach or deck cleaner on the fence. Let it dwell 5–10 minutes to break down mildew and algae at the surface level.

2

Power Wash at Correct Pressure

Work with the grain, keeping the nozzle 12–18 inches from the surface. Use a 25° or 40° fan tip — never a 0° pinpoint nozzle on wood.

3

Apply Wood Brightener (Optional)

A deck brightener (oxalic acid) neutralizes tannin stains and restores the natural wood tone after cleaning. Especially helpful for gray, weathered boards.

4

Allow to Dry Completely

Wait 24–48 hours before applying any stain, sealer, or paint. Staining wet wood traps moisture and causes premature peeling.
