One of the biggest perks of choosing Trex for your deck is how low-maintenance it is—but “low” maintenance doesn’t mean “no” maintenance. To keep your Trex deck looking as beautiful as the day it was installed, a little regular care goes a long way.

At Decked Out Tennessee, we’ve built countless Trex decks for homeowners in Franklin, Brentwood, Nolensville, and across Middle Tennessee. Here are our top tips to help you protect your investment and keep your composite deck clean, safe, and looking brand new for years to come.

🧽 1. Clean It Seasonally (or As Needed)

Trex is resistant to mold, mildew, and stains—but it still needs occasional cleaning.

What to do:

• Sweep off dirt, leaves, and debris regularly.

• Use a soft-bristle brush and warm, soapy water (or a composite deck cleaner) to scrub the surface.

• Rinse thoroughly with a garden hose—no power washing needed!

Pro Tip: Clean your deck at least twice a year: once in spring and again in fall.

🧼 2. Tackle Stains Promptly

While Trex is highly stain-resistant, spills from food, grease, or oils can leave marks if left untreated too long.

What to do:

• Clean up food, wine, or sauce spills immediately.

• For oily spots, use a degreasing dish soap and warm water.

• Avoid harsh chemicals like bleach, acetone, or abrasive scrubbers.

Tip for grill owners: Place a grill mat or splatter guard under your cooking station.

🍃 3. Watch for Mold & Mildew in Shaded Areas

Composite materials resist mold better than wood, but damp, shaded spots can still grow surface mold over time—especially in Tennessee’s humid climate.

What to do:

• Improve airflow and sunlight exposure when possible.

• Wash the area with a solution of warm water and vinegar or a Trex-approved mold cleaner.

• Ensure proper drainage underneath the deck to prevent pooling moisture.

⚙️ 4. Inspect Hardware and Fasteners

Even if the boards look great, hardware can wear down over time.

What to do:

• Check railings, fasteners, and joists once or twice a year.

• Tighten any loose screws or connectors.

• If you see corrosion or movement, give us a call for a quick inspection.

🛑 5. Avoid These Common Mistakes

To protect your Trex deck from accidental damage, keep these do’s and don’ts in mind:

🚫 Don’t drag heavy furniture across the boards—lift instead
🚫 Don’t use metal snow shovels (they can scratch the surface)
🚫 Don’t use sand, salt, or ice melt products not rated safe for composites
🚫 Don’t pressure wash above 3100 psi or too close to the boards

Why Trex is Still a Smart Choice for Middle Tennessee

Thanks to its fade resistance, long lifespan, and minimal upkeep needs, Trex remains one of the most popular decking materials we install throughout Franklin, Brentwood, and Nolensville. With just a bit of seasonal TLC, your deck will continue to look stunning—and perform like new—for decades.
