Shelves are difficult to slide or bind when pulling bottles out.

Safety first: Remove bottles before working on shelves to prevent breakage.

Steps to improve shelf movement:

• 1. Remove and inspect shelves: Check for warping, cracks, or bent metal rails.
• 2. Clean glides: Wipe rails and glides with a damp cloth and mild detergent to remove sticky residue.
• 3. Do not lubricate with oil: Avoid petroleum-based lubricants that can attract dust. If needed, use a dry silicone spray sparingly.
• 4. Replace damaged components: Install new shelf assemblies or rails if they are bent or warped.
