Q: How do I clean my composite deck?

Jerry, get ready to clean less and relax more – composite decking only needs periodic cleaning. 

Detailed cleaning instructions can differ depending on the type of decking and brand.

Periodic cleaning
Composite decking is low-maintenance – not to be confused with "no maintenance" – but like any product exposed to the outdoor elements, it should be cleaned. We recommend periodic cleaning to help maintain the beauty of your deck. Using warm water and mild dishwashing detergent is usually a good way to clean small areas. For a periodic maintenance cleaning of the entire deck surface, some people prefer an eco-friendly cleaner like Corte Clean to keep their deck looking new. Be sure to use as directed by the manufacturer.

Power Washing
A power washer can also be used when cleaning a TimberTech® deck. The recommended psi settings are different for wood-plastic composite decking, capped composite decking and PVC decking, so be sure to view the deck care and cleaning page on our website and adjust the pressure based on the manufacturer’s instructions. Always take the proper safety precautions when operating a power washer, and use as directed by the manufacturer. Enjoy your clean deck, Jerry!
