Pressure Wash a Wood Deck – Step by Step Guide

Pressure Wash a Wood DeckCleanliness is important not only for your health but also to protect the value of your home. One way to do this is by pressure washing a wood deck with soap and water. This will remove any dirt or debris that has accumulated on the surface of the wooden planks, making them appear brighter and more attractive.

How to Pressure Wash a Wood Deck?

Pressure washing can be accomplished in one hour with these steps:

  1. Start by putting on safety glasses and rubber gloves.
  2. Mix together a few drops of dish soap with one gallon of water in the sprayer tank, adding more if necessary to fill it up completely.
  3. Put on ear protectors or headphones in order to avoid noise damage from the pressure washer’s motor running at full speed.
  4. Power on the machine and give it a few minutes to warm up.
  5. When the surface is nice and wet, turn off any other outside water sources such as hoses or sprinklers so you don’t get them mixed in with your cleaning solution.
  6. Spray the deck using an even sweeping motion from one end of the deck to the other, keeping the sprayer nozzle about a foot away from it.
  7. When finished with one section of your deck, move onto another and repeat as needed until you’ve covered every square inch of wood.
  8. Allow time for any cleaning solution or standing water on the surface to dry before allowing children and pets to walk on it.
  9. If any mold is present in crevices between boards, soak them with cleaner and scrub using an old toothbrush or other bristly brush.
  10. Rinse off any remaining soap residue with plain water and allow the deck to dry completely before using.
  11. Keep in mind that this process may cause wood coloration to lighten slightly, but it will regain its original appearance within a few days as dirt is removed from between boards and the wood dries.
