Many homeowners replace their existing, dilapidated decks with composite decking. Composite decking holds up much better than traditional wood decking. It needs very little, if any, repair work. All composite decking needs is some cleaning once in a while to keep it looking good. Cleaning a composite made deck is easy. It takes only a couple of hours depending on the size of your deck.
With a Pressure Washer
Make sure to close all the windows on the side of the house containing the deck to prevent water and dirt from getting into the house.

Hook up your pressure washer to the outside spigot.
Prepare and set up the cleaning solution according to the manufacturer's instructions of your pressure washer.
Rinse the entire deck off using plain water.
Use the pressure washer, loaded with the cleaning solution, to spray the entire deck with soapy water.
Examine the deck. Use a long-handled, stiff scrub brush to remove any stubborn stains, mold or mildew.
Spray the deck again with the pressure washer loaded with the cleaning solution.
Rinse the deck off with fresh, clean water.
Repeat the process if necessary.
Without a Pressure Washer
Sweep all the loose debris off your deck. Make sure to remove all the cobwebs from all the corners as well.
Fill a bucket with hot water. Check the manufacturer's instructions and add the appropriate amount of cleaner for the amount of water in your bucket.
Scrub the entire surface of your deck using the long-handled scrub brush. Use a rag or handheld scrub brush to clean off the railings and other hard-to-reach areas.
Hook up the garden hose to your outdoor spigot. Rinse off the deck thoroughly with fresh water.
