Learn simple steps to clean and maintain your Kinto Day Off Tumbler, keeping drinks at the perfect temperature and preserving its sleek Japanese design.

Quick answer

Hand wash your Kinto Day Off Tumbler with mild dish soap and warm water, and dry it fully before storing to keep it clean and performing well.

Why hand washing beats the dishwasher

The Kinto Day Off Tumbler’s double-wall insulation keeps drinks hot or cold for up to six hours. Dishwasher cycles can stress the seal and finish over time, so hand washing is the safer choice to preserve both looks and performance.

Abrasive scrubbers and harsh chemicals can scratch the soft-touch exterior or damage the lid’s seal. Stick to a soft sponge and gentle detergent to keep the tumbler looking as refined as the day you bought it.

Step-by-step cleaning and care

Rinse immediately after use: After finishing your drink, rinse the tumbler with warm water to remove residue before it dries. This prevents stains and makes the deep clean easier. Don’t let coffee or tea sit for hours—rinse right away to avoid buildup.
Hand wash with mild soap: Use a soft sponge or cloth with a few drops of mild dish soap and warm water. Gently clean the inside, outside, and the lid, paying attention to the rim and crevices where residue can hide. Avoid abrasive pads and strong detergents—they can scratch or dull the finish.
Dry completely before storing: Rinse off all soap, then shake out excess water and dry the tumbler and lid with a lint-free towel. Leave the lid off and let it air dry fully before reassembling. Trapped moisture can cause odors or mildew, so make sure everything is bone dry.
Handle tough stains with baking soda: For stubborn coffee or tea stains, make a paste of baking soda and water. Apply it with a soft cloth, gently rub, then rinse thoroughly. Baking soda is gentle enough for the interior and won’t harm the insulation.
Store with the lid off: When not in use, keep the tumbler open or with the lid slightly ajar to allow airflow. This prevents odors and keeps the seal fresh. Storing with the lid sealed can trap moisture—keep it ventilated.
