Using this mug is super easy. Just open the Press - In Lid, pour in your favorite hot drink, and close the lid. To make sure it keeps your drink hot for a long time, try to pre - heat the mug by filling it with hot water for a few minutes before adding your beverage. When it comes to cleaning, hand - wash it with mild dish soap and warm water. Avoid using abrasive sponges as they might scratch the mug. Also, don't put it in the dishwasher or microwave. If you're not using the mug for a while, store it in a dry place with the lid off to prevent any odors from building up.
