5. Maintenance
Proper care will extend the life and appearance of your sleeve:
- Cleaning Exterior: For general cleaning, wipe the exterior surface with a soft, damp cloth. Use mild soap if necessary, then wipe with a clean, damp cloth to remove any residue. Allow to air dry completely.
- Cleaning Interior: Gently shake out any dust or debris from the faux-fur lining. A lint roller can also be used for light cleaning. Avoid harsh chemicals or abrasive cleaners.
- Stain Removal: For stubborn stains, spot clean with a gentle fabric cleaner, following the product instructions. Test on an inconspicuous area first.
- Avoid Excessive Moisture: Do not submerge the sleeve in water or machine wash, as this may damage the materials and padding.
6. Troubleshooting
Most issues with the Incase Classic Universal Sleeve are minor and can be resolved with simple steps:
- Zipper Sticking: If the zipper becomes stiff, apply a small amount of zipper lubricant or a graphite pencil lead to the teeth. Avoid forcing the zipper.
- Device Not Fitting: Ensure your device is a 15-inch model or smaller. Forcing a larger device into the sleeve can cause damage to both the sleeve and the device.
- Minor Scratches/Marks: For light marks on the exterior, gentle cleaning as described in the Maintenance section is usually sufficient.
