7. Maintenance
Regular cleaning and proper care will ensure the longevity and appearance of your medicine cabinet.
- Cleaning Mirrors and Glass: Use a soft, damp cloth and a mild glass cleaner. Avoid abrasive cleaners or harsh chemicals that can damage the mirror surface or frame finish. Spray cleaner onto the cloth, not directly onto the mirror.
- Cleaning Frame and Interior: Wipe surfaces with a soft, damp cloth. For stubborn spots, a mild, non-abrasive household cleaner can be used, followed by rinsing with a clean, damp cloth and drying thoroughly.
- Hinge Care: The hinges are designed for durability. Avoid applying excessive force when opening or closing the door. If hinges become stiff, a small amount of silicone-based lubricant can be applied, but avoid contact with mirror surfaces.
- Shelf Adjustment: Periodically check that glass shelves are securely seated on their clips.
8. Troubleshooting
This section addresses common issues you might encounter with your medicine cabinet.
| Problem | Possible Cause | Solution |
|---|---|---|
| Door does not close smoothly or quietly. | Hinges may need adjustment or cleaning. | Check hinge screws for tightness. Clean hinges and apply a small amount of silicone lubricant if necessary. Refer to the full installation guide for hinge adjustment procedures. |
| Shelves are wobbly or fall out. | Shelves not properly seated on clips, or clips are loose. | Ensure shelf clips are fully inserted into the support holes and are level. Re-seat the glass shelves firmly onto the clips. |
