What to know about cleaning pressure-treated wood

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.

When to book deck cleaning for pressure-treated wood

  • Gray, weathered boards
  • Green or black growth and slippery spots
  • Stain that is peeling or worn through
  • Dark spots under planters and furniture
  • Mildew between composite boards

Why it gets dirty

  • Sun breaking down the wood surface (it turns gray)
  • Shade, leaves and moisture feeding mildew
  • Old stain or sealer wearing unevenly
  • Pollen and dirt trapped in the gaps

Easy upkeep between cleanings

  • Clear the gaps between boards with a putty knife so water drains
  • Sweep often and keep leaves off the deck
  • Move planters and rugs now and then
  • Check for loose boards, nails and soft spots before anyone washes it
