Quick answer
Wash your stainless steel tumbler by hand with mild dish soap and a soft sponge, then dry it immediately with a lint-free cloth. Store it with the lid off in a dry, ventilated spot to prevent moisture buildup and odors. Avoid the dishwasher if the tumbler has a vacuum seal or painted finish.
Why hand washing matters for stainless steel tumblers
Stainless steel itself is dishwasher-safe, but many tumblers have a vacuum insulation layer, a powder-coated exterior, or a printed design that can degrade in high heat or harsh detergents. Hand washing preserves the finish and the seal, keeping your drinks cold or hot longer. A soft sponge and warm, soapy water are all you need.
How to remove stubborn odors and stains
Coffee, tea, or leftover smoothie can leave a lingering smell inside a tumbler. To freshen it, fill the tumbler with a mixture of warm water and a tablespoon of baking soda, let it sit for 15 minutes, then scrub gently with a bottle brush. For tough stains, use a paste of baking soda and water. Rinse thoroughly and dry immediately.
Drying and storage tips to prevent damage
After washing, dry the tumbler completely with a soft towel. Never store it with the lid on while still damp, as trapped moisture can cause mold or a musty smell. Store the tumbler upright with the lid off in a clean cabinet. If you stack multiple tumblers, place a soft cloth between them to avoid scratching the exterior.
Steps for cleaning and storing your tumbler
- Rinse immediately after use: Pour out any leftover liquid and rinse the tumbler with warm water. This prevents residue from drying and sticking. Don't let coffee or tea sit for hours—it makes cleaning harder and can stain the interior.
- Hand wash with mild soap and a soft sponge: Add a drop of mild dish soap and scrub the inside, outside, and lid with a soft sponge or bottle brush. Avoid abrasive pads that can scratch the finish. Check the lid's silicone gasket for trapped debris; remove it periodically for a thorough clean.
- Dry completely before storing: Use a lint-free cloth to dry every part, including the lid and the rim. Let the tumbler air-dry upside down on a dish rack for an hour if you're not in a hurry. Never store the tumbler with the lid on while still damp—this is the number one cause of mold and odors.
- Store with the lid off in a dry place: Place the tumbler upright in a cabinet or on a shelf with the lid beside it. Keep it away from direct heat or sunlight. If you stack tumblers, separate them with a soft cloth to avoid scratches on painted or printed exteriors.
