Why Our Deck Cleaning Is Different
Anyone with a pressure washer can blast a deck with high pressure, but that approach often damages wood fibers, creates splinters, and leaves decks looking streaky and uneven. Our process is designed to safely remove dirt, mildew, and weathered wood while restoring the natural beauty of the wood grain underneath. The result is a deck that looks professionally restored, not just pressure washed.
The NWPWS 3-Step Wood Cleaning Process
💧
Step 1: Pre-Soak
We begin by thoroughly soaking your wood deck with water. This critical first step fills the pores in the wood, preventing it from absorbing the cleaning detergent in the next step. By saturating the wood first, we ensure the detergent works on the surface to lift dirt and grime rather than soaking deep into the wood where it could cause problems.
💧
Step 2: Detergent Application and Cleaning
Next, we apply a specialized wood cleaning detergent formulated specifically for deck restoration. The detergent is allowed to dwell on the surface for 10-15 minutes while we keep the surface wet. During this time, the solution breaks down dirt, mildew, algae, and weathered wood fibers. For heavily soiled areas, we agitate the surface with a deck brush to ensure thorough cleaning. After the dwell time, we rinse the deck thoroughly, removing all contaminants and loosened material.
💧
Step 3: Neutralization and Brightening
This final step is what transforms a clean deck into a beautifully restored one. We apply a wood neutralizer and brightener to the wet surface, again allowing it to dwell for 10-15 minutes while keeping the surface moist. This solution neutralizes the alkaline cleaning detergent, restores the wood's natural pH balance, and opens the wood grain to reveal the fresh, bright wood underneath. The result is a deck that looks newly sanded—naturally light, even-toned, and ready to accept stain or sealant if desired. We finish with a thorough rinse, leaving your deck clean, bright, and restored
Not Your Budget Deck Cleaning Service
We're upfront about our pricing because we're proud of the results we deliver. Our 3-step process costs more than a basic pressure washing, and there's a reason for that. We use professional-grade products, proven techniques, and the time required to properly restore your deck. The investment pays off in superior results that last longer and protect your deck better than any $100 quick clean ever could.
The Results Speak for Themselves
Our 3-step process doesn't just clean your deck—it restores it. The difference between our professional restoration and a basic pressure washing is immediately visible. Your deck will have:
-
Even, natural wood color throughout
-
Visible wood grain and texture
-
No splinters or damaged fibers
-
Bright, fresh appearance
-
Surface ready for stain or sealant application
-
Professional-quality results that last
-
Why Invest in Professional Deck Cleaning?
Your deck is a significant investment and a key feature of your outdoor living space. While budget services might save money upfront, they often damage wood fibers, create uneven cleaning patterns, and require frequent redoing. Our professional process protects your investment while delivering superior results.
We can also do our 3 step process on non painted wood railings, stairs and fences.

Perfect Timing for Portland's Climate
Portland's wet winters create ideal conditions for mildew and algae growth on decks. Spring and early summer are perfect times for deck restoration, giving your wood time to dry thoroughly before applying stain or sealant. Regular cleaning every 1-2 years maintains your deck's beauty and prevents deterioration.
Post-Cleaning Recommendations
After our 3-step cleaning process, your deck will need 48-72 hours of dry weather to cure completely before staining or sealing. This fresh, clean, brightened surface provides the ideal foundation for protective coatings. We're happy to provide recommendations for staining and sealing, though these services are separate from our cleaning process.
