Maintenance and Care
To ensure the longevity and effectiveness of your LTGEM headphone case, follow these maintenance guidelines:
- Cleaning Exterior: Wipe the exterior of the case with a soft, damp cloth. For stubborn dirt, a mild soap solution can be used, followed by wiping with a clean, damp cloth. Allow to air dry completely.
- Cleaning Interior: Gently wipe the velvet interior with a dry, soft cloth. For minor spills, lightly dampen a cloth with water and blot the affected area. Do not saturate the interior.
- Zipper Care: Keep the zipper free from dirt and debris. If the zipper becomes stiff, a small amount of zipper lubricant or wax can be applied.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the case materials.
- Storage: Store the case in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
