Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Streaks after rinse | Uneven cleaner application or quick drying | Rewash in small sections with a slow, uniform rinse | Clean on a cloudy day; keep sections small |
| Discoloration after cleaning | Using bleach-based products | Stop and switch to a non-bleach deck cleaner for TimberTech | Always use non-bleach formulas recommended for capped composites |
| Surface scuffing or dulling | High-pressure nozzle or abrasive brush | Lower pressure; use soft-bristle brush only | Test in a hidden area first |
| Persistent mildew | Poor ventilation or heavy shade | Apply a mold and mildew remover per label and improve airflow | Trim surrounding vegetation to reduce shade |
Common Mistakes To Avoid
- Using a bleach-based deck cleaner on capped TimberTech boards, which can fade color.
- Using a high-pressure washer with a narrow nozzle that gouges the surface.
- Skipping a test patch, leading to unexpected discoloration.
- Neglecting to rinse thoroughly, leaving cleaner behind and attracting dirt.
Being precise with product choices helps preserve TimberTech’s aesthetic and functional longevity. Always prioritize materials labeled safe for composite decking.
Tips For Best Results

- Use a dedicated soft-bristle brush to prevent micro-scratches on the cap layer.
- Schedule annual or biennial cleaning, especially in areas with heavy pollen or mildew-prone climates.
- Rinse thoroughly and allow full drying before applying any protective foliage or furniture.
