6. Maintenance
6.1. Cleaning the Cabinet
- Mirrored Surfaces: Use a soft, lint-free cloth and a non-abrasive glass cleaner. Spray cleaner onto the cloth, not directly onto the mirror, to prevent liquid from seeping into edges.
- Aluminum Frame: Wipe with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage the finish.
- Shelves: Glass shelves can be removed and cleaned with mild soap and water or a glass cleaner. Ensure they are completely dry before reinserting.
Regular cleaning will help maintain the high-quality finish and extend the life of your cabinet.
6.2. Hinge Care
The slow-close hinges are designed for long-term performance. If the door action becomes stiff or noisy, a small amount of silicone-based lubricant can be applied to the hinge points. Do not use oil-based lubricants.
7. Troubleshooting
