9 Tips for Pressure Washing a Deck

It’s about halfway through the summer season and it’s time to finally check “cleaning the deck” off your to-do list. Without a proper cleaning, mildew, mold and dirt can get trapped in the wood of your deck. But sometimes a long nap in the hammock is more tempting than spending the afternoon scrubbing. I find that the best way to get the job done right is by using a pressure washer.

If you’re wondering whether it is more beneficial to own or rent a pressure washer, we’ve laid out the details. Either way, it’s best to wash your deck annually, but depending on how much wear and tear there is you may need to clean it more often. Once you find the best pressure washer for you, follow these helpful tips for proper cleaning without damaging your wood.

  1. Be sure to wear protective gear such as closed shoes, splash proof googles and gloves to avoid harmful chemicals.
  2. Some cleaning solutions may suggest covering or watering nearby plants before using the washer, be sure to check your cleaning solution’s instructions and safety guidelines before using.
  3. Engage the trigger away from the deck’s surface and then bring the pressure washer onto the wood.
  4. Be sure the nozzle has an angle between 40 and 60 degrees, never spray directly down onto the wood.
  5. Power wash in a gentle sweeping motion back and forth.
  6. Hold the washer about 8 to 12 inches away from the surface of the deck.
  7. Work from the inside out. Start in the corners and bring the debris out to the edge of the deck.
  8. Allow 24 hours to dry after washing.

That’s all there is to it – after a few quick steps the deck will be clean and ready for more summer fun.
