Keeping Your Vacuum Flasks Performing at Peak Efficiency

- Baking Soda & Warm Water: Mix 2 tablespoons with warm water, let soak for 30 minutes to dissolve mineral buildup.
- White Vinegar Rinse: Neutralizes odors naturally without scratching the inner electropolished surface.
- Air Dry Completely: Store with lid detached to prevent moisture trapping.
