<human>:  How do I clean a wood deck?
<bot>: To clean a wood deck, you will need to use a pressure washer with a detergent or cleaning solution. Before cleaning, make sure to remove any loose debris and sweep the surface. Once the loose debris has been removed, begin pressure washing the surface, starting at one end and working your way to the other. Make sure to overlap your sprays slightly and keep the pressure washer at a low setting to avoid any damage to the wood surface. After you have finished pressure washing, rinse the surface with clean water and let it dry fully before applying any sealants or surface treatments.
