Annually cleaning your deck will help prolong its life, a light detergent that contains an anti-fungal agent is best.

Avoid using high pressure waterblasters or harsh chemicals.


Any coating or oil applied may require subsequent recoating. Refer to coating manufactures maintenance schedule.


Removing any items that will trap water underneath them (furniture, pot plants, etc.) for the duration of winter will extend the life of your deck and help keep it looking great.
