How To Pressure Wash Your Wood Deck Without Damaging It

Wooden decks are beautiful and they can give you vital living space outdoors. But when they begin to look old and worn, they can actually detract from the value of your home. Bring the shine back to your deck with a good scrubbing.

Pressure washing is a fast and effective way to remove all kinds of built up grime and stains on your deck’s surface, making it look new again in just hours. Of course, knowing the proper way to use a power washer on wooden decks can help keep you from damaging it. Here are a few basic tips to help you through the pressure washing process without worrying about causing pits, cracks or worse damage.

Cleaning the Wood Surface

Cleaning off stains, dirt and mildew begins with a good sweeping. Use a broom to brush off any debris from the surface. Then, using a medium power washer, aim the nozzle at a 40-degree angle and gently mist the surface.

Once wet, you can apply a cleaning solution that is designed for pressure washers and wooden surfaces using a low-pressure soap nozzle. While the pressure washer can easily lift up small stains, you may need to use a scrub brush on tougher ones, especially those found in hard to reach areas like corners.

When power washing your deck, make sure you follow the manufacturer’s directions

Tip: Be sure to follow the manufacturer’s directions on the cleaning solution bottle carefully and do not allow the cleaner to dry on the surface of the deck.

Once you have cleaned all of the spots and stains from the deck, rinse with clear water on a medium- to high-pressure setting. You should always spray with the grain of the wood. When using a higher pressure, always test a small area to ensure that the pressure is not too strong for your deck.

Tackling Tough Jobs

Decks that have not been cleaned in several years or that have weathered severely may need  more than a basic cleaning. Wood stripper is a common product that can help revitalize even the most worn deck surface.

When stripping an older deck be sure to follow these basic steps:

  • Begin by rinsing the deck with a medium-powered spray.
  • Next, spray the surface with a wood stripper that is designed to clean your wood type. Follow the directions on the stripper bottle carefully.
  • Let stand for about 15 minutes, but be sure that it does not dry.
  • Rinse clean.
  • Once you have sprayed off the stripper solution with clear water, apply wood brightener to the deck using the same light spray technique.
  • Again, feel free to use a scrub brush to deal with tough to reach spots like corners.
  • Let stand for 15 minutes.
  • Rinse clean.

Always let a newly cleaned deck dry for about 48 hours before using.
