There are many reasons to choose a TimberTech composite deck, from incredible fade and stain resistance, to attractive hues and realistic grain patterns, to unrivaled protection from mold, mildew, and weathering. But perhaps one of the greatest benefits for those looking for high style, low maintenance decking is this: cleaning composite decking is super simple. TimberTech capped composite and capped polymer boards require only minimal care (think the occasional wash-and-rinse) to stay looking great. We’ll highlight how to clean composite decking, what tools you’ll need, and when to break out the brush.
Because we believe your deck should be enjoyed, not maintained.
What You’ll Need to Clean Composite Decking
TimberTech® DeckCleaner™
Cleaning your TimberTech capped composite or capped polymer deck is straight-forward and doesn’t require the power washing, re-staining, or resealing of traditional wood decks. That said, because all exterior products will encounter exposure to everyday spills, dust, pollen, and foot traffic, it’s a good idea to clean periodically. We recommend TimberTech DeckCleaner™*, our solution for seasonal cleanup, spots, and everyday spills.
Here are the tools you will need to clean your TimberTech composite deck, as compared to the laundry list needed for pressure-treated lumber:

A garden hose will work for spot cleaning, but regular power-washing will be necessary to cut through accumulated mold, mildew, and staining.
You may need to sand your deck after power-washing, which means even more time, labor, and expense. |
*Note: TimberTech DeckCleaner™ is formulated, field tested, and approved for cleaning TimberTech AZEK® decking or porch, TimberTech PRO® decking, TimberTech EDGE® decking, and TimberTech composite railing. On average, one gallon diluted with one part cleaner to three parts water will clean approximately 1,000 square feet of surface area.
Tips for How to Clean Composite Decking
General upkeep for all decks will involve the following:
- Periodically sweeping leaves, dirt, debris, dust, and pollen from your porch.
- Spot cleaning paw prints, mud, or other tracked material, especially near doors and stairs.
- Wiping up any small spills that might come with outdoor entertaining.
Sometimes, though — and certainly as your deck transitions from winter to spring — it’s time to break out the brush. It will be important to know how to clean composite decking after it’s been exposed to any harsh weather (both extreme heat and cold), or after any standing moisture or natural material has sat on the deck (think sand, blown-in dirt, snow, or sleet). You’re ready to reach for TimberTech® DeckCleaner and an appropriate brush (remember: natural-fiber for TimberTech AZEK decking; nylon for TimberTech PRO and EDGE).
