How To Pressure Wash A Deck

Pressure washing your deck is an essential task to keep it clean and well-maintained. Over time, dirt, grime, and mildew can accumulate on your deck, making it look dull and unattractive. In this article, we will guide you on how to pressure wash a deck effectively.


Before you start pressure washing your deck, you should take some necessary precautions to ensure your safety and prevent any damage to your property. Here are some things you should do:

Clear the Deck

Remove all the furniture, grills, and other items from your deck. This will prevent them from getting damaged during the pressure washing process.

Cover Nearby Plants

Cover any plants or shrubs near your deck with plastic sheeting or a drop cloth. This will protect them from the high-pressure water.

Wear Protective Gear

Wear protective gear like safety goggles, gloves, and boots to protect yourself from debris and chemicals.

Pressure Washing the Deck

Now that you have prepared your deck, it’s time to start pressure washing. Here are the steps you should follow:

Choose the Right Pressure Washer

Choose a pressure washer that is suitable for your deck’s material and size. A gas-powered pressure washer is ideal for larger decks, while an electric pressure washer is suitable for smaller decks.

Apply Deck Cleaner

Apply a deck cleaner to your deck to remove dirt, grime, and mildew. Follow the manufacturer’s instructions on how to apply the cleaner.

Set the Pressure Washer

Set the pressure washer to a low-pressure setting to prevent damage to your deck’s surface. A pressure setting of 1200-1500 PSI is ideal for most wooden decks.

Start Pressure Washing

Start pressure washing your deck by holding the wand at a 45-degree angle and working in the direction of the wood grain. Keep the nozzle at least 6 inches away from the deck’s surface to avoid damaging it.

Rinse the Deck

After pressure washing your deck, rinse it thoroughly with clean water to remove any remaining dirt or debris.
