Travel mugs are often not dishwasher safe due to the materials they're made from and their insulation properties. Many have double-walled construction designed to keep drinks hot or cold, which can be damaged by the high heat and harsh detergents of a dishwasher, leading to decreased insulation effectiveness. The seals and adhesives used in these mugs can also be compromised. To prolong the life of your travel mug, hand washing with warm, soapy water is recommended.
