Care and Maintenance
The Keter Marvel+ 270L Outdoor Storage Box is designed for zero maintenance due to its durable, weatherproof, and fade-free resin construction. However, occasional cleaning is recommended to maintain its appearance.
- Cleaning: Wipe down the exterior with a damp cloth and mild soap solution. Rinse with clean water and dry thoroughly. Avoid abrasive cleaners or harsh chemicals, as these can damage the material.
- Inspection: Periodically check all connections and hinges to ensure they remain secure.
- Winter Storage: While weather-resistant, storing the box in a sheltered area during extreme winter conditions can further extend its lifespan.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lid does not close properly. | Obstruction in the box; hinges misaligned; panels not fully clicked into place. | Remove any obstructions. Check hinge alignment and re-seat if necessary. Ensure all wall panels are securely assembled. |
| Water inside the box. | Lid not fully closed; extreme weather conditions; improper assembly. | Ensure the lid is completely closed. Verify all panels are correctly assembled and sealed. While weather-resistant, prolonged exposure to heavy rain or standing water may allow some moisture ingress. |
| Box feels unstable. | Assembled on an uneven surface; panels not fully clicked into place. | Move the box to a flat, level surface. Re-check all panel connections to ensure they are fully engaged. |
