Deck Cleaning · Step 4 of 10
In this video
After sweeping, prepare your chosen commercial deck cleaner by filling a pump sprayer according to product instructions. Liberally apply the cleaner to all wood surfaces that you intend to treat, including the deck floor and both the inside and outside surfaces of the wood railings. Allow the cleaner to sit and penetrate the wood for approximately 10 minutes, or as directed by the product's instructions. Following the dwell time, rinse the cleaner off with cold water using a garden hose equipped with a nozzle. For heavily soiled areas or stubborn stains, you may opt to repeat the cleaning process, this time using a scrub brush to agitate the cleaner before rinsing.
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.
