Composite decking is one of the most popular choices for homeowners at Auburn Deck Company who want a beautiful, low-maintenance outdoor space. Unlike wood, it doesn’t require annual staining or sealing, but it still needs occasional care. With the right cleaning routine, you can keep your composite deck looking like new for years.
If you’re wondering how to clean composite decking the right way, follow this step-by-step guide.
Step-by-Step: How to Clean a Composite Deck
1. Clear and Sweep the Deck
Move furniture, grills, rugs, and planters off the deck. Sweep away leaves, dirt, and other debris to prepare for washing.
2. Rinse the Surface
Use a garden hose with a spray nozzle to rinse away loose dirt. While pressure washers can be used carefully, a strong setting may damage the boards—stick with a gentle spray for routine cleaning.
3. Prepare a Cleaning Solution
At Auburn Deck Company, we use TimberTech brand composite decking. TimberTech® DeckCleaner™, is a manufactured cleaning solution to clean composite decking with. To use, shake the cleaning solution and mix according to the instructions on the label. Information on TimberTech® DeckCleaner™ – https://www.timbertech.com/product/timbertech-deckcleaner/
4. Scrub the Decking Boards
Start with small sections to clean to prevent the cleaning solution from drying/evaporating. With a soft-bristle brush, scrub along the grain of the boards allowing surface contact for 30-60 seconds. Pay extra attention to high-traffic areas and spots where mildew or grime may collect.
5. Rinse Thoroughly
Once scrubbed, rinse your deck completely with clean water. Make sure no cleaning or soap residue remains, as it can create a slippery surface once dry.
6. Let It Dry and Reset
Allow your deck to air dry before putting furniture and rugs back in place.
Quick Tips for Composite Deck Maintenance
- Clean spills quickly to prevent permanent staining.
- Avoid rugs with rubber backing, which can trap moisture and cause discoloration.
- Deep clean at least twice a year, preferably in spring and fall.
