Maintaining your deck as a homeowner is essential for its longevity and aesthetic appeal. Dirt, grime, and other buildups can wreak havoc on the wood and make the deck appear unattractive. One effective way to clean your deck is pressure washing; this quick process effectively removes dirt, stains, and grime from the deck while protecting it at the same time. This article will guide you on how to pressure wash a deck while keeping its condition intact.

Best Way to Pressure Wash a Deck: Steps You Can Follow

Step 1: Prepare Your Deck for Pressure Washing

Before you begin pressure washing your deck, you should do a few things first. Remove all furniture, plants, and other items from the area, then sweep away loose debris like leaves and twigs with a broom. Cover any electrical outlets, lights, or other components to protect them from water damage, and finally, test out the pressure washer in an inconspicuous area to ensure it functions correctly.

Step 2: Choose the Appropriate Pressure Washer

Choosing an appropriate pressure washer for your deck is paramount. Electric pressure washers work best for small decks, while gas-powered pressure washers offer excellent coverage on larger surfaces. Ensure the pressure washer you select has the appropriate PSI (pounds per square inch) and GPM (gallons per minute) settings; high PSI could damage your surface, so opt for a lower set instead.

Step 3: Utilize the Appropriate Pressure Washer Nozzle

When pressure washing a deck, the nozzle you use matters. A 25-degree nozzle is ideal as it provides excellent pressure without damaging the wood. Steer clear of 0-degree nozzles, which may damage wood and cause permanent harm.

Step 4: Utilize a Deck Cleaner

Apply a deck cleaner before pressure washing your deck for optimal results. A deck cleaner will remove dirt, stains, and grime from its surface. Be sure to select an effective deck cleaner compatible with your pressure washer and wood type; follow its manufacturer’s instructions for application.

Step 5: Pressure Wash Your Deck

Once you’ve applied the deck cleaner, it’s time to pressure washing your deck. Begin at the highest point and work your way down; keep the pressure washer nozzle about 6-12 inches from the wood surface and use long sweeping motions to eliminate dirt and grime. Avoid lingering in one spot, as this could damage wood fibers.

Step 6: Rinse Your Deck

Once you’ve pressure washed your deck, it’s time for a thorough rinse. Use a garden hose or the low setting on your pressure washer to rinse any residual deck cleaner or dirt. Ensure this step is taken thoroughly, as leaving residue can lead to further damage if not thoroughly rinsed away.

Step 7: Allow Your Deck to Dry

Please wait until your deck has completely dried before walking on it or replacing furniture and other items. Depending on weather conditions, it could take an hour up to a full day for it to dry completely.
