Pressure washing your wood decking is an effective way to restore its natural beauty and extend its lifespan. Over time, dirt, grime, mold, and algae can build up on your deck, making it look dull and worn out. Learning how to pressure wash wood decking properly ensures that you clean it without causing damage to the wood’s surface.
Whether you’re prepping your deck for a fresh coat of stain or just giving it a seasonal clean, understanding the right techniques is essential. In this guide, we’ll walk you through step-by-step instructions on how to pressure wash your deck safely, from choosing the correct pressure settings to the best cleaning solutions. With the right approach, your deck can look brand new again without splinters or scratches. Let’s dive into how to get started!
How To Pressure Wash Wood Decking?
1. Prepare Your Deck Area
Before you start pressure washing, it’s crucial to prepare your deck area to ensure a smooth and effective cleaning process. Begin by removing all furniture, planters, and any other items from the deck. Sweep the deck thoroughly to remove loose debris like leaves and dirt. If there are any stubborn stains or spills, treat these areas with a suitable cleaner and allow it to sit for a while to break down the grime.
Cover any surrounding plants, grass, or surfaces with plastic sheeting or tarps to protect them from potential damage caused by the pressure washer or cleaning solutions. Ensure that all electrical outlets and light fixtures on the deck are covered to prevent water from getting into them. Proper preparation will make the cleaning process more efficient and prevent any accidental damage to your surroundings.

2. Choose the Right Pressure Washer
Selecting the right pressure washer for your wood decking is essential to avoid damaging the wood. For most wood decks, a pressure washer with a PSI (pounds per square inch) rating between 1,200 and 1,500 is ideal. Higher pressure settings can cause the wood to splinter or strip away the protective finish. Choose a pressure washer with adjustable pressure settings so you can control the intensity based on the condition of your deck.
Additionally, using a pressure washer with a wide spray nozzle is beneficial, as it disperses the water more evenly and reduces the risk of damaging the wood. If you’re unsure which pressure washer to use, consult the manufacturer’s recommendations or seek advice from a professional to ensure you select the appropriate equipment.
3. Select the Right Cleaning Solution
Choosing the appropriate cleaning solution is crucial for effectively removing stains and dirt without harming your wood deck. Look for a cleaner specifically designed for wood decks, which often contains ingredients that safely break down mold, mildew, and grime. Avoid using bleach, as it can damage the wood and potentially harm surrounding plants.
If you prefer a natural approach, you can mix a solution of water and white vinegar or use baking soda for lighter cleaning tasks. Test the cleaning solution on a small, inconspicuous area of the deck first to ensure it does not cause discoloration or damage. Follow the manufacturer’s instructions for mixing and applying the cleaner to achieve the best results.
4. Apply the Cleaning Solution
Once you’ve selected the appropriate cleaning solution, it’s time to apply it to your wood deck. Using a garden sprayer or a brush, evenly distribute the cleaning solution over the entire surface of the deck. Start from one end and work your way to the other, ensuring that you cover all areas, including hard-to-reach spots.
Allow the solution to sit on the deck for the recommended time specified by the cleaner’s instructions. This dwell time helps to loosen the dirt and stains, making them easier to wash away. Be cautious not to let the solution dry out, as this can make cleaning less effective. If necessary, reapply the solution to any areas that have dried before rinsing.
5. Pressure Wash the Deck
With the cleaning solution applied and allowed to sit, it’s time to start pressure washing the deck. Begin by adjusting the pressure washer to the appropriate PSI setting (between 1,200 and 1,500) and attach a wide spray nozzle. Hold the nozzle at least 12 inches from the deck’s surface to prevent damage. Start washing at one end of the deck and work in a consistent pattern, such as left to right or top to bottom.
This ensures even cleaning and prevents streaks. To guarantee full coverage, slightly overlap each pass. Move slowly and steadily, allowing the water to rinse away the cleaning solution and dirt. Be mindful of any areas where the wood might be more delicate or prone to splintering, and adjust your technique accordingly.
6. Rinse and Inspect
After pressure washing the deck, thoroughly rinse the entire surface with clean water to remove any remaining cleaning solution and debris. Use a garden hose or a separate rinse setting on your pressure washer to ensure that no residue is left behind. Look over the deck to see if there are any places that were overlooked or that require more care.
If you find any stubborn stains or grime, apply a bit more cleaning solution and repeat the pressure washing process on those areas. Once the deck is fully rinsed and clean, allow it to dry completely before proceeding with any further treatments, such as sealing or staining. This drying period is essential to ensure that the wood absorbs any additional treatments evenly.

7. Apply Sealer or Stain (Optional)
After your deck is thoroughly cleaned and dried, you may choose to apply a sealer or stain to protect the wood and enhance its appearance. A sealer helps to protect the wood from moisture, UV rays, and general wear and tear, while a stain adds color and can further protect the wood. Choose a sealer or stain that is specifically designed for wood decks and follow the manufacturer’s instructions for application.
Typically, you’ll need to apply the product using a brush or roller, working in small sections to ensure even coverage. Allow the sealer or stain to dry according to the recommended drying time before replacing furniture and using the deck. Regular maintenance, including periodic cleaning and reapplication of sealer or stain, will keep your deck looking great and extend its lifespan.
Conclusion
Pressure washing your wood deck can significantly improve its appearance and longevity. By following the right steps, such as using the appropriate pressure and cleaning solutions, you can effectively clean the deck without damaging it. Regular maintenance through pressure washing will keep your deck looking its best and prevent long-term issues like mold growth or wood rot. With proper care, your wood decking will remain a beautiful and functional space for years to come.
