Cleaning your insulated tumblers is easy. Use a brush to scrub the interior and exterior with warm water and dish soap. You can dry it with paper towels or a kitchen towel. If you’re not pressed for time, you can also leave it to air dry on a dish rack. Hand washing is necessary to preserve the powder-coated finish and keep your tumbler looking new. The extreme heat of the dishwasher can be harmful to the tumbler’s exterior, so always prioritize washing your cup by hand. Thankfully, we make it easy to care for your tumbler!
