how to clean and seal composite decking defy wood stain
the first step is to remove any mildew dirt or stains that are currently on the deck. for cleaning i highly recommend using a power washer on composite decks as opposed to just a garden hose and a scrub brush. a power washer will not only help get things cleaner than scrubbing by hand but will also do it much faster. just remember anything that is not removed by cleaning will not be able to be removed once the project is finished. so take your time and thoroughly clean the deck.
