Frequently Asked Questions
How often should I deep-clean my insulated tumbler to prevent smells and mold?
For everyday use, rinse and wash the tumbler after each use, remove and dry the gasket, and use a straw brush for straws. Do a weekly deep clean: soak the interior and removable lid parts in warm water with a teaspoon of baking soda or a mild vinegar solution, scrub with a brush, rinse thoroughly, and air-dry completely to prevent mold and odors.
Can I put my tumbler in the dishwasher?
Check the manufacturer's guidance: stainless interiors are often dishwasher-safe, but powder-coated exteriors and decorated finishes may fade or chip in the dishwasher. To protect finish and gasket life, hand-wash the exterior and lids when possible and reserve dishwasher use for interiors only if the manufacturer explicitly allows it.
What’s the safest way to clean and care for the lid gasket?
Remove the silicone gasket if the lid allows it, soak it in warm soapy water, scrub with a small brush, rinse, and air-dry fully before reassembly. Inspect gaskets for cracks or permanent deformation—replace them if they no longer seal or if discoloration persists after cleaning.
I see small rust spots — how do I remove them and stop more from forming?
Light surface rust can often be removed with a paste of baking soda and water or a short soak in white vinegar, followed by scrubbing with a non-abrasive brush. Rinse thoroughly and dry immediately. Prevent recurrence by drying the tumbler and lid parts after washing, avoiding prolonged contact with salty liquids, and storing with lids off or inverted to allow airflow.
Are straw and brush accessories worth having?
Yes—steel straws and narrow brushes let you clean long, narrow openings and hard-to-reach crevices that regular sponges miss. Models that include brushes reduce friction for maintenance and make it easier to keep straws, lids, and gasket channels free of residue and mold.
