Looking for pressure washing for pressure-treated wood in your area? We look at the surface first, choose the right method and pressure for it, and give you a price before any work starts. With pressure-treated wood, the right approach is low-pressure wash.

How we clean it

Low-pressure washCleaning method
Usually 500-1,200 PSI with a wide fan tipPressure

Cleaning solution: An oxygen-based or sodium percarbonate wood cleaner, then an oxalic acid brightener.

Cleaning pressure-treated wood safely

Pressure-treated pine is the most common deck and fence wood. It grays, mildews and gets slippery when wet. A wood cleaner does most of the work, and a brightener afterward restores the wood's color and helps new stain soak in.

Avoid: High pressure and narrow tips, which leave furry, gouged boards and lap marks.

How often: Clean yearly; restain every 2-3 years.

Is it time for pressure washing for pressure-treated wood?

  • Driveway or walkways look dark, gray or streaky
  • Green or black growth in shaded areas and along edges
  • Slippery surfaces after rain
  • Oil, rust or tire marks you can't scrub out
  • You're getting ready to sell, seal or paint

Where the grime comes from

  • Dirt and pollen that settle into the pores of concrete
  • Mold, mildew and algae in damp, shaded spots
  • Oil and fluid drips from vehicles
  • Rust from sprinklers, furniture and fertilizer
  • Tire marks and general foot traffic

Safe steps for homeowners

  • Sweep off leaves and loose debris so they don't stain
  • Blot fresh oil drips with cat litter or an absorbent right away
  • Point sprinklers away from walls and walkways to cut down on rust and hard-water stains
  • Rinse pollen off with a garden hose during heavy pollen season

Common mistakes to avoid

  • Etched lines and 'zebra stripes' from holding a narrow tip too close
  • Water forced into window frames, door sills and siding laps
  • Damaged plants and lawns from chemical runoff
  • Injuries: a zero-degree tip can cut skin, and wet surfaces are slippery
