5. Maintenance and Care
Cleaning
To clean your Coolife softshell luggage, use a soft cloth dampened with mild soap and water. Gently wipe down the exterior fabric. For tougher stains, a specialized fabric cleaner for luggage may be used, following the product's instructions. Avoid harsh chemicals or abrasive materials that could damage the fabric or finish.
Storage
When not in use, store your luggage in a cool, dry place away from direct sunlight. For optimal space-saving, the smaller pieces can be nested inside the larger ones. Ensure all zippers are closed before storing.
6. Troubleshooting
Zippers
If zippers become stiff, apply a small amount of zipper lubricant or wax to the teeth and gently work the zipper back and forth. Avoid forcing stuck zippers.
Wheels
If wheels become difficult to roll, check for any debris (hair, lint, etc.) caught in the wheel mechanism. Clean as necessary. Ensure wheels are not bent or damaged. For persistent issues, contact customer support.
Telescopic Handle
If the telescopic handle sticks, ensure no items are obstructing its mechanism inside the lining. Gently extend and retract it a few times. Avoid excessive force.
