Many lids are not dishwasher safe. Hand wash with mild soap and warm water to preserve the seal and finish.
For stubborn coffee stains, use a baking soda paste or white vinegar. Soak overnight, then scrub.
Disassemble lid parts if possible. Use a small brush to clean the sip hole and gasket. Rinse thoroughly.
Our team found that the best compact mugs combine vacuum insulation with a truly leak-proof lid; the lid is often more important than the body for everyday satisfaction.
When cleaning, pay extra attention to the lid gasket-it's the most common spot for mold. Remove and wash it separately at least once a week.
