Is RTIC Tumbler dishwasher safe?
Sometimes — with care
RTIC Tumblers are generally not recommended for the dishwasher due to potential damage to the vacuum seal and exterior finish.
Why
RTIC tumblers are made of double-wall vacuum-insulated stainless steel with a powder-coated exterior. The high heat and harsh detergents in dishwashers can degrade the powder coating and compromise the vacuum seal over time. While some users report success, the manufacturer advises hand washing to preserve performance and appearance.
How to wash it
Hand wash with mild soap and warm water using a soft sponge or cloth. Rinse thoroughly and dry immediately to prevent water spots.
