6. Care and Maintenance

• Cleaning: Wipe the lock's exterior surfaces with a soft, damp cloth. Avoid abrasive cleaners or solvents, as these can damage the finish.
• Lubrication: Periodically apply a small amount of graphite-based lubricant or a silicone-based spray lubricant into the keyway and the latch mechanism. Do not use oil-based lubricants, as they can attract dirt and dust.
