Proper Maintenance For Composite Outdoor Deck
No decking material is maintenance-free. Caring for composite outdoor deck isn’t the same as caring for wood decking. Here are some tips that can help you maintain your composite outdoor deck. Sweep all loose debris off the deck. Remove any sticks or leaves that may be stuck in the cracks between boards. Mix the composite outdoor deck cleaner as directed, or combine mild soap and hot water in a bucket. Scrub the surface of the deck, using a deck brush. A long-handled brush is easiest to work with and will prevent back strain. The brush should have soft bristles. Spray the deck off, using the hose. Remove all soap residue. Remove or lighten mill marks with acetone (fingernail polish remover). Wet a cotton ball, then rub gently in a circular motion to remove the mark. Visible mill marks can be avoided with careful installation.
Lighten or remove rust stains by using a cleaning product that contains oxalic or phosphoric acid. Apply the product full-strength and let it soak into the stain for 10 to 15 minutes. Remove patio furniture from composite outdoor deck and grills at the end of the summer to avoid rust stains accumulating over the winter. Scrub oil stains with a soft bristle brush a household degreaser, then rinse. Oil stains can seep into the material and will be permanent if not addressed immediately. Remove stains from berries or red wine with bleach and water. Mix 1/4 cup bleach with 1 cup warm water, then use a soft bristle brush in a circular motion. Stains from berries may be permanent.
