Wood decks are subject to natural weathering and require regular cleaning. Each deck requires an individual maintenance interval, depending on location, use intensity and personal preferences.
Decking will form a biofilm that will hold water and reduce the speed of drying of the board, and a large build-up of such a layer should be prevented. Regular cleaning will be needed to control the build-up of such a biofilm.
Under normal circumstances, an Accoya deck should be cleaned thoroughly once a year, preferably in spring, with some light cleaning throughout the year. More frequent cleaning may be necessary if the deck is permanently shaded, e.g. on the north side of a house or in the immediate vicinity of bushes, large trees and forests.
Accoya decking can be cleaned with a stiff brush and clear water. The process is improved by wetting it before cleaning, as the soaking softens the biofilm. For more persistent stains, a cleaning agent can be used, we recommend a cleaning agent with a PH value below nine and to rinse the decking thoroughly with clear water.
Planed surfaces are easier to clean than rough sawn surfaces. The use of a high-pressure cleaner is absolutely unsuitable for wooden decking and is expressly NOT recommended. The high-pressure water jet can damage the wooden boards, regardless of the wood species. Please protect your wood deck with a cover when using a high-pressure cleaner for other materials in the immediate vicinity.
