Cleaning composite decking twice a year , usually in spring and autumn.This is quick and easy to do, requiring just a hose, a soft brush and a bucket of soapy water or a pressure washing water gun .

  • Begin by weeping dirt and debris on the decking and cleaning up spills from leaves, foods, oils and wine. Never use harsh bristle or metal wire, it will scratch and damage the deck’s surface.
