Scrub with a Brush — Inspect and Spot Treat
Part of project
Deck Cleaning · Step 7 of 10
In this video
While the cleaning solution is still wet and active on the deck surfaces, use a stiff-bristle deck brush to vigorously scrub all wood components. This includes the main deck planks, handrails, and balusters. The mechanical action of scrubbing helps to agitate and dislodge deeply embedded dirt, stubborn mildew, and pervasive algae that the chemical solution has loosened. Focus particular effort on areas that appear most severely soiled or have persistent green or black patches. Ensure you scrub with the grain of the wood to maximize cleaning effectiveness and prevent accidental damage to the wood fibers.
FAQs
What's the biggest mistake beginners make when using a pressure washer on a deck, and how can I avoid it?
The most common mistake is using too much pressure or holding the nozzle too close, which can damage the wood fibers and leave permanent marks. Always start with a low-pressure setting and a fan-tip nozzle (like 25-40 degrees), keeping the wand moving and maintaining a consistent distance of at least 12 inches from the deck surface. Test on an inconspicuous area first to find the right balance.
How can I protect my plants and surrounding landscaping from the deck cleaning solutions?
Before applying any cleaner, thoroughly wet down nearby plants, shrubs, and grass with water. You can also cover delicate plants with tarps or plastic sheeting to create a physical barrier. After cleaning and rinsing the deck, re-rinse any affected vegetation with fresh water to dilute residual chemicals.
Is a pressure washer absolutely necessary for this project, or can I clean my deck effectively with just a scrub brush and hose?
While a pressure washer significantly speeds up the process and provides a deeper clean, it's not strictly necessary for lightly soiled decks. For smaller decks or those with only surface dirt, a good stiff scrub brush, deck cleaner, and a garden hose with a strong nozzle can be effective. However, heavy grime, mold, or mildew will be much tougher to remove manually.
The project lists an estimated time of 4 hours. Is this realistic, and what factors might make it take longer?
The 4-hour estimate is a good baseline for a moderately sized deck with average dirt. Factors that can increase this time include larger deck size, severe staining or mildew growth requiring multiple cleaner applications, intricate deck designs, or the optional step of applying a sealant or stain. Drying time also needs to be factored in before applying any finishes.
