Surya Yadav

The deck becomes a focal point for backyard gatherings and relaxation during spring and summer. However, weathering and constant foot traffic can cause a deck to appear dirty, grey, and worn. Reviving a tired wooden deck to look freshly stained and sealed once again is possible with pressure washing.

Pressure washing is a powerful cleaning method, but it’s essential to get it right. The force of the water can clean surfaces effectively, yet if used incorrectly, it can cause damage. For wooden decks, it’s crucial to strike a balance. You’ll need a pressure washer, the proper cleaning solution, and a gentle touch.

Here are some tips to refresh your deck’s appearance using a power washer, aside from hiring professionals similar to As New Again Pressure Washing:

  1. Choose The Right Pressure Washer And Settings

Selecting the appropriate pressure washer and its settings is a crucial step in deck maintenance. Here are some additional considerations:

  • Pressure Range: The typical residential pressure washer starts at higher settings, usually around 1,300 to 2,400. It’s crucial to start with the lowest setting available on your pressure washer and gradually increase the pressure only if necessary, closely observing how the word reacts.
  • Nozzle Type: The nozzle is essential in pressure control. A wider angle nozzle (around 40 to 60 degrees) offers a gentler spray, which is preferable for wood surfaces. It disperses pressure over a broader area, reducing the risk of damage.
  • Test Before Proceeding: Before fully committing to cleaning your entire deck, test the washer on a small, inconspicuous area. This helps ensure the pressure and nozzle setting won’t harm the wood.

You can effectively clean your deck without inflicting damage by carefully selecting the suitable pressure washer and adjusting its settings. Remember, the aim is to rejuvenate your deck, not to strip it bare.

  1. Prepare Your Deck For Washing

Before you start the washing process and spend time outside, thoroughly preparing your deck is essential. Start by removing all furniture, grills, planters, and other items. This clears the space, allowing you to access every nook and cranny. Sweep the deck thoroughly to remove loose debris, leaves, and dirt. This step is crucial, as it prevents dirt from turning into mud while washing, which can be harder to remove.

Also, inspect the deck for any loose nails or screws and tighten them as needed. It ensures a smooth cleaning surface and bolsters safety. Addressing these small repairs beforehand can make a significant difference in the cleaning process, providing an even and effective wash.

  1. Select The Perfect Cleaning Solution

Choosing the best cleaning solution is crucial for effective and safe deck cleaning. Here are some additional considerations:

  • Eco-Friendly Options: Consider environmentally friendly cleaners. These solutions are gentle on your deck and safe for plants and pets around your outdoor area. Look for products labeled as biodegradable or non-toxic.
  • Specific Formulations For Wood: Some cleaning solutions are specifically formulated for wood, catering to its unique properties. These specialized cleaners help maintain the integrity of the wood while effectively removing dirt and stains.

Always follow the manufacturer’s instructions for mixing and applying the cleaner. It ensures optimal results and maintains the health of your deck. Remember, the right solution makes all the difference in rejuvenating your wooden surfaces without causing harm.

  1. Master The Technique

When you’re ready to start, begin in a less noticeable area to get a feel for the pressure washer. Hold the nozzle about two feet from the deck surface and use even, sweeping motions. It’s like painting—consistent, overlapping strokes yield the best results. Avoid lingering too long in one spot to prevent etching the wood.

  1. Address Stubborn Stains And Mold

For tough stains or mold, you might need a bit more elbow grease. Apply a deck cleaner and gently scrub the affected area with a soft brush. Be cautious not to scrub too hard, which can damage the wood’s surface.

  1. Rinse And Dry

After washing, thoroughly rinse your deck to remove any remaining cleaner. This step is crucial to ensure no chemical residue is left behind that might damage the wood over time. Then, allow the wood to dry completely, which typically takes about 48 hours. This drying period is essential, as applying sealant or stain to damp wood can lead to uneven absorption and a less-than-ideal finish.

  1. Seal And Protect Your Deck

Once dry, consider sealing your deck. A quality sealant can protect the wood from moisture and UV damage, extending its life and beauty. Apply the sealant according to the manufacturer’s instructions for the best results.

  1. Maintain Your Deck Post-Washing

Deck care involves regular maintenance to keep it looking great year-round. Sweep it regularly and rinse off any spills promptly. Repeat the pressure washing process every couple of years to remove accumulated dirt and grime.


Revitalizing your wooden deck is a rewarding project. With the right tools, techniques, and a bit of patience, you’ll create an inviting outdoor space that’s ready for years of enjoyment. Remember, the key to a successful pressure washing project is a gentle approach and regular upkeep. Happy cleaning!
