6. Maintenance
Proper care will ensure the longevity and appearance of your Keter Comfy Deck Box.
- Cleaning: Clean the deck box regularly with a soft cloth, mild soap, and water. Avoid abrasive cleaners, harsh chemicals, or stiff brushes, as these can damage the resin surface.

7. Troubleshooting
If you encounter any issues with your Keter Comfy Deck Box, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lid does not close properly. | Obstruction inside, misaligned hinges, or uneven surface. | Remove any obstructions. Check hinge alignment and re-seat if necessary. Ensure the box is on a level surface. |
| Water inside the box. | Lid not fully closed, extreme weather conditions, or damaged seal. | Ensure the lid is securely closed. Check for any cracks or damage to the box or lid. While water-repellent, prolonged exposure to heavy rain may allow some moisture ingress. |
