When using the included vacuum - insulated cup, just pour your drink into it, and it'll stay hot for about 20 minutes. As for maintenance, wash the flask and the cup with mild dish soap and warm water after each use. Don't use abrasive cleaners as they might scratch the stainless steel. Also, make sure to dry the flask thoroughly to prevent rust. Store it in a cool, dry place when not in use. Avoid dropping the flask as it might damage the vacuum insulation and affect its performance.
