Decks & balconies
Clean a composite deck
Composite decking does not need painting or sealing, but debris removal, cleaning and structural checks still matter.
Recommended timingSeasonally or as needed
What to do
- Sweep leaves and debris from the surface and between boards so water can drain.
- Clean spills promptly and wash periodically with the tools, cleaner and pressure limits approved for the exact product line.
- Trex generally recommends soap and water; TimberTech instructions vary by product, so keep the original care guide with the home records.
- Inspect the supporting structure, guards, stairs and fasteners even when the deck boards look new.
