Since composite wood decking is low maintenance, periodic washing with soap and water will remove surface dirt and chalk that accumulate on the composite deck surface. This will also prevent the buildup of pollen and debris that can cause mold and mildew growth.
Pressure washers (with fan-tip nozzle) should be used for wetting and rinsing only. Pressure washers should not be used to “blast off” soiling agents; attempting to do so can drive the dirt deeper into the composite deck boards. In most cases, applying the cleaning agent with a pump sprayer and scrubbing thoroughly with a synthetic brush will clean the surface.
Grime, Ground-in Dirt, Rust
In most cases, soap and water will maintain the appearance of composite decking material. If grime, ground-in dirt or rust marks become a problem, use a cleaning product with an oxalic acid base. Do not use bleach, abrasive cleansers or pads when cleaning.
Mold
Mold may form on any surface where moisture is prevalent, where there is heavy shading, or where pollen and debris are allowed to collect. To remove mold, use conventional deck washers or cleaners that contain sodium percarbonate and detergent. These cleaners can be found at most home centers.
