Instead of scrubbing on your hands and knees, cleaning a wood deck is best done with a pressure-washer. When using this machine, it’s important to understand its true power, as holding the nozzle too close to the deck can splinter the wood. If water isn’t enough to clean the gunk of your deck, you may want to add in a chemical stripper or brightener. Finally, sometimes it may be necessary to sand your deck after you pressure-wash it since the water’s abrasive properties may erode the wooden fibers.

Key Takeaways:

  • A pressure washer is powerful enough to etch brick, so it can ruin a deck if not properly used.
  • Soft woods can withstand pressure of around 500-600 psi, while harder woods should not go above 1200 psi.
  • After the wood dries, you may need to sand the entire deck.

“Work with the grain by feathering the spray lengthwise, parallel to the deck boards, and overlapping each area slightly.”
