Our vacuum-insulated stainless steel tumblers should not be used in the microwave, oven, or dishwasher, as these can affect their insulation properties. We recommend hand washing instead.
Other stainless steel products are dishwasher safe but should not be used in the microwave.
When washing by hand, please avoid abrasive cleaners or steel wool.
To prevent rust, be sure to wash and dry your items thoroughly after each use, and store them away from other metals.
For more information, please check the product page or refer to the JOURNAL article for cleaning instructions specific to your tumbler.
