Before You Start

Prepare the area by removing cushions and other accessories. Test any cleaner in an inconspicuous spot for colorfastness. Follow the manufacturer’s instructions for dilution and dwell time. Allow furniture to dry completely before use. Important: never use abrasive pads, bleach, ammonia, or aggressive solvents on Trex surfaces, as they can dull color or scratch the finish.

Estimated time: 20–40 minutes for a typical cleanup, longer for large sets or heavily soiled pieces.

Step-By-Step: How To Clean Trex Furniture

  1. Clear surfaces: Remove cushions, planters, and any loose debris from the furniture.
  2. Rinse lightly: Use a garden hose to rinse away loose dirt and dust from all surfaces.
  3. Apply cleaner: Lightly spray or apply Trex furniture cleaner for composite decking to the affected areas, following product directions.
  4. Gently scrub: Use a non-abrasive scrub brush or a plastic bristle deck cleaning brush to work the cleaner in circular motions, focusing on stains.
  5. Rinse thoroughly: Remove all cleaner residue with clean water, ensuring no suds remain on the surface.
  6. For stubborn spots: Let the cleaner sit for the specified dwell time, then re-scrub and rinse again.
  7. Dry and inspect: Wipe with a soft microfiber cloth and let the furniture air dry. Check for remaining stains and repeat if necessary.
  8. Deeper cleaning: If needed, use a pressure washer safe cleaner in accordance with safety guidelines for a deeper clean, maintaining a gentle setting and keeping the nozzle at a safe distance.
  9. Protective finish: Once dry, consider applying furniture protectors or mats to minimize wear and keep surfaces looking fresh.
  10. Routine maintenance: Plan monthly cleanings or quarterly deep cleans depending on exposure and usage.

Troubleshooting

Symptom Likely Cause Fix Prevention
Faded or dull color after cleaning Harsh cleaners or improper rinsing Switch to a dedicated composite cleaner and rinse thoroughly Follow product directions; avoid solvents
Stubborn gray film on surface Hard water deposits or mineral buildup Reapply cleaner and rinse with distilled water Rinse after use; wipe dry

Common Mistakes

  • Using steel wool or metal brushes, which can scratch the surface
  • Skipping a rinse, leaving cleaner residue that can dull finish
  • Using bleach or ammonia-based cleaners on Trex furniture
  • Neglecting to dry surfaces fully, which can lead to mildew growth

Tips For Best Results

  • Test cleaners on a hidden area first to confirm colorfastness
  • Work from top to bottom to prevent dirty runoff onto cleaned areas
  • Use circular motions with a soft brush for even cleaning
  • Maintain a regular cleaning schedule to prevent buildup
  • Store cushions during cleaning to protect fabric from cleaners

Call A Professional
