Homes & Gardens advises clearing furniture, pots, leaves and loose debris before washing a wooden deck. The article warns that pressure washing can raise wood fibers, making the apparently quick method a source of damage. A mild, compatible soap solution and non-scratching brush offer a more controlled approach.

Clean a Wood Deck Gently Before Reaching for Pressure

Work along the grain and protect nearby plants in accordance with the cleaning product instructions. Follow the deck and finish manufacturer's guidance rather than assuming every timber tolerates the same solution or amount of water. Rinse as directed and allow the surface to dry before returning objects, so cleaning does not leave moisture trapped beneath planters or furniture.

A soft-bristled approach can remove surface grime without the fiber damage associated with aggressive washing.
