Everyday Items People Forget About
Insulated Mugs and Tumblers
Many insulated mugs and tumblers rely on a sealed space between their inner and outer walls to provide insulation.
For some products, dishwasher exposure can damage seals, finishes or other components. If water gets into a sealed insulating cavity, the item’s ability to maintain temperature can be compromised.
However, some modern insulated products are specifically designed to be dishwasher safe, so check the manufacturer’s instructions before deciding.
Your “keeps coffee hot for 6 hours” mug could eventually become just… a mug if its insulation is damaged.
