Is Insulated Tumbler dishwasher safe?
Sometimes — with care
Insulated tumblers are often dishwasher safe, but it depends on the specific model and manufacturer's instructions.
Why
Many stainless steel insulated tumblers are dishwasher safe, but the insulation can be compromised by high heat, and some lids or coatings may not withstand the dishwasher. Double-walled vacuum insulation can lose its effectiveness if exposed to high temperatures repeatedly.
How to wash it
Check the manufacturer's label; if dishwasher safe, place on the top rack away from heating elements. For best longevity, hand wash with mild soap and a soft sponge.
