Before You Start

- Rinse the deck with a garden hose to wet the surface and reduce cleaner contact time on dry spots.
- Mix a non-bleach deck cleaner for capped composite TimberTech with water according to label directions in a bucket or sprayer.
- Apply the cleaner evenly using a soft bristle brush to agitate dirt at the surface and between deck boards. Avoid aggressive scrubbing that could dull the finish.
- For stubborn stains, allow the solution to dwell for 5–10 minutes, then scrub once more with the brush. Do not let cleaners dry on the surface.
- Rinse with a electric pressure washer gentler nozzle for composite deck TimberTech, starting from the house outward. Keep the nozzle at a safe distance (about 8–12 inches) to avoid gouging the surface.
- If mold or mildew appears, apply a mold and mildew remover for TimberTech decking to affected areas and scrub gently before a thorough rinse.
- Inspect boards for remaining dirt or staining; repeat cleaning on any stubborn spots. Allow the deck to dry completely before replacing furniture.
- Dispose of rinse water away from delicate plants and lawns, following local guidelines for runoff.
- For regular upkeep, perform cleaning biannually or after heavy foliage shedding seasons to maintain a uniform appearance.
- Optional: After drying, consider applying a protective deck cleaner or rejuvenator if recommended by TimberTech for your product line.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Streaks after cleaning | Uneven application or insufficient rinse | Reapply cleaner to streaked areas and rinse thoroughly | Consistent brushing and full surface rinse each time |
| Surface dullness after cleaning | Overly aggressive scrubbing or harsh cleaner | Switch to soft-bristle brush and non-bleach cleaner | Choose milder products and avoid abrasive tools |
| Discoloration or whitening | Undiluted cleaner or extended dwell time | Rinse immediately and dilute next time; follow label timing | Follow manufacturer’s dwell-time guidelines |
| Stubborn mildew remains | Deep mildew growth or shaded, damp area | Apply mold and mildew remover and re-clean with gentle brushing | Improve airflow and sun exposure with trimming or pruning around deck |
Common Mistakes
- Using a high-pressure nozzle too close to the deck, causing surface damage.
- Applying bleach or harsh chemicals that can discolor or degrade the finish.
- Letting cleaner dry on boards before rinsing.
- Over-saturating boards in humid climates, prolonging drying times.
Tips For Best Results
- Schedule cleaning during mild weather to ensure thorough drying and prevent stains from setting.
- Keep pets and kids off the deck until it dries completely after cleaning.
- Test any cleaner on a small, inconspicuous area first to confirm colorfastness.
- Use a nozzle with a fan pattern and maintain a steady, sweeping motion to avoid streaks.
