How to Power Wash Your Composite Deck

Supplies You’ll Need and What to Do

Now that it’s nice outside, we all want to spend as much time enjoying the weather as we can. It’s hard to feel relaxed lounging on your deck or having guests over when your deck is covered in mildew, mold, and old stains. To make quick and thorough work of cleaning, you can wash your composite deck with a power washer.

How to Power Wash Your Composite Deck

What You’ll Need

  • A power washer
  • Access to a hose/spigot
  • A cleaning solution

What to Do

1. Prep your space: It might seem easier to move furniture and your grill around the deck as you go, but you will be able to do a more thorough cleaning if you take everything off. It is also helpful to spray down the deck before you get started.

2. Choose the right settings: The pressure you need to wash your composite deck will likely not be more than 3,100 pounds per square inch. This is a high enough force to damage other home items and even cause harm to yourself. Your hose should be set to a 40- to 60-degree angle. Of course, read the manual from your power washer’s manufacturer and your composite deck care manual for specific setting instructions.

3. Use the right motion: “Sweep” the deck, starting at your home and working the water stream toward the far side of the deck. This helps ensure there aren’t any missed spots, which will show when you are finished because the chemical solution does part of the work. You can “feather” your motion to help mask the starts and stops of the sweep. You do this by going over the overlap part with quick, small sweeping motions. The pressure washer should never be closer than 8″ from your deck.
