Cleaning composite decks is relatively easy. Here’s a basic process:

1. Start by removing loose debris using a broom or leaf blower.
2. Mix warm water with mild soap or composite deck cleaner according to the manufacturer’s instructions.
3. Use a soft-bristle brush or sponge mop to scrub the surface in small sections.
4. Rinse thoroughly with water to remove any residue from cleaning solutions.
5. For tougher stains or mold/mildew, specialized composite deck cleaners or mildew removers may be required. Follow the product instructions carefully and consider seeking professional assistance if needed.
