Trex composite decking has redefined outdoor spaces for homeowners around the globe. Its durability, stunning designs, and low-maintenance allure make it a standout choice for decks that blend functionality and beauty. However, like any home feature, regular cleaning is essential for maintaining its charm and extending its lifespan.

This guide takes you through everything you need to know about cleaning Trex composite decking, from understanding its key benefits to mastering the art of deck care.

Introduction to Cleaning Trex Decking

Benefits of Trex Composite Decking

Trex composite decking combines sophistication and strength, offering a surface that resists fading, staining, and structural wear over time. Engineered from reclaimed wood and recycled plastics, Trex stands out as a sustainable option for eco-conscious homeowners.

The low-maintenance nature of Trex decks means less time scrubbing and more time enjoying—but minimal maintenance doesn’t mean no maintenance. A regular cleaning routine keeps your Trex deck board looking pristine and functional for years.

Why Cleaning is Important for Your Deck

Cleaning isn’t just about aesthetics; it’s about safeguarding your investment. Leaves, dirt and debris from the deck can wear down the deck’s surface over time, while moisture-trapping grime might encourage mold or mildew growth on the deck board. Proper cleaning ensures that your deck continues to be a welcoming hub for relaxation and gatherings without the risk of long-term damage.

Essential Cleaning Tools and Products

Here’s what you’ll need to clean your Trex deck effectively and safely: 

  • Brushwith soft or medium bristles for manual scrubbing
  • Hoseor bucket of water for rinsing
  • Pressure washerfor deep cleaning (optional)
  • Composite deck cleanerfor removing stains and grime
  • Deck brightener and stain remover productsfor tough blemishes
  • Mopfor spot cleaning

Composite Deck Cleaner

Choose a cleaner formulated specifically to preserve composite decking. These solutions efficiently lift dirt and stains without causing discoloration or damage to your composite decking surface. 

Pressure Washer and Power Washer

While a pressure washer can be useful for deeper cleaning, it must be used cautiously. Stick to a pressure setting of 1200 psi or lower to avoid damaging the deck surface.

Deck Brighteners and Stain Removers

For more persistent stains—like mildew, food spills, or grease—deck brighteners and specialized stain removers are indispensable. Many are biodegradable and safe for Trex decking.

How to Clean Your Trex Composite Deck: Step-by-Step Guide

Preparing Your Deck for Cleaning

Before you begin, remove any furniture, grills, or planters that may obstruct your cleaning process. Use a broom to sweep away loose debris like soil, leaves, or twigs.

Cleaning the Deck Surface

Using a Pressure Washer

If you’re using a pressure washer for a thorough clean, set it at 1200 psi or less. Hold the nozzle approximately 8–10 inches away from the deck surface and work with smooth, sweeping motions to remove dirt. 

Scrubbing with a Cleaning Product

Apply your composite deck cleaner across the deck surface, focusing on tough spots and high-traffic areas. Use a soft-bristled brush to scrub gently in circular motions. Avoid metal brushes, as they may scratch the decking material. 

Removing Stains and Dirt

Dealing with Oil and Grease Stains

To handle spills like oil or grease, apply an appropriate stain remover immediately. Alternatively, a vinegar solution can be effective for lifting grease without harsh chemicals.

Removing Debris and Dirt

For everyday cleaning, a handheld broom or blower can help remove debris caught in the crevices of your deck. Regular sweeping helps mitigate grime buildup.

Drying the Deck Surface

Rinse thoroughly to remove all cleaner residue from the deck. Allow it to air dry completely before placing furniture or stepping on it to avoid reintroducing dirt.

How to Maintain Trex Decking for Long-Term Cleanliness

Regular Cleaning and Maintenance Tips

For optimal results, clean your deck at least twice a year—preferably during spring and fall. Beyond these deep cleans, simply rinse or spot-clean as needed to ensure a well-kept appearance. 

Keeping Your Trex Deck Pristine Between Cleanings

Preventative care goes a long way. Sweep regularly to keep dirt from settling into the surface. For spot cleaning, a quick application of composite deck cleaner followed by rinsing can refresh your deck in no time.

Common Trex Deck Cleaning Issues and Solutions

Dealing with Ice and Snow on Trex Decking

Trex decking performs admirably in colder climates, but avoid metal shovels that can gouge the surface when clearing snow from the deck. Opt for a plastic shovel instead. Steer clear of de-icers containing harsh chemicals that might harm the deck. 

What Causes Trex Composite Decking to Fade?

Prolonged exposure to sunlight or harsh weather can cause the composite surface to slightly fade over time. However, proper care—like regular cleaning and using protective sealants—can maintain its vibrant appearance. 

How NOT to Clean a Trex Deck

Avoid abrasive cleaning tools, excessive pressure from a washer, or harsh chemicals like bleach, as they can strip the surface of its protective finish and cause damage. These harsh chemicals can cause the deck to discolor or lighten the decking surface.
