Maintenance and Care
Proper care will extend the life and maintain the appearance of your L/B Sports Bag.
- Cleaning the Exterior: Wipe the polyurethane polyester exterior with a soft, damp cloth. For stubborn stains, use a mild soap solution and then wipe clean with a damp cloth. Avoid harsh chemicals or abrasive cleaners.

Troubleshooting
Here are solutions to common issues you might encounter:
| Problem | Possible Cause | Solution |
|---|---|---|
| Zipper sticks or is difficult to close. | Fabric caught in zipper; dirt or debris in zipper teeth. | Carefully pull any caught fabric away. Clean zipper teeth with a small brush or damp cloth. Apply a small amount of zipper lubricant if necessary. |
| Insulation seems ineffective. | Bag not fully closed; no ice pack used; extreme external temperatures. | Ensure zipper is fully closed. Use an ice pack for optimal cooling. Avoid leaving the bag in direct sunlight or hot environments for extended periods. |
| Unpleasant odor inside the bag. | Food residue or moisture left inside. | Thoroughly clean the interior with mild soap and water. Air dry completely with the bag open. Placing baking soda in an open container inside the bag overnight can help absorb odors. |
