Quick answer
Yes, your Kelso Tumbler is dishwasher safe, but the best way to keep it leak-free and fresh is to hand-wash the lid and rinse the cup after each use.
Why care matters for the leak-proof spout
The Kelso Tumbler's silicone sipper spout has a built-in valve that stops water from flowing when no one is drinking. That clever design is what makes it spill-proof for car rides and park days. But food particles and sticky residues can build up around the valve over time, which may affect its seal. Regular cleaning keeps the valve working properly and extends the life of your tumbler.
Frequently asked questions about Kelso Tumbler care
Is the Kelso Tumbler dishwasher safe?
Yes, the cup is top-rack dishwasher safe. For the lid, hand-washing is recommended to preserve the silicone valve and prevent warping. If you do put the lid in the dishwasher, place it on the top rack away from the heating element.
How do I clean the silicone spout valve?
Remove the silicone spout from the lid (it pulls off easily). Wash it with warm soapy water and a soft brush or cloth. Rinse thoroughly and let it air dry completely before reattaching. This prevents mold and keeps the valve flexible. Check the valve every few weeks for debris or stiffness.
Can I use bleach or harsh cleaners?
No. Avoid bleach, chlorine, and abrasive cleaners. They can damage the silicone and plastic parts. Stick to mild dish soap and warm water. For stubborn stains, a baking soda paste works well.
How do I prevent odors in the tumbler?
Rinse the cup immediately after each use, especially if you've had milk, juice, or other non-water drinks. For lingering smells, fill the cup with a mixture of warm water and white vinegar (1:1 ratio), let it sit for 15 minutes, then wash as usual. Never leave liquid sitting in the tumbler for more than a few hours.
What about the straw? Does it need special care?
The Kelso Tumbler comes with a reusable straw. Clean it with a straw brush and warm soapy water after each use. Let it dry fully before storing to prevent bacterial growth. The straw is also dishwasher safe on the top rack. Replace the straw if it becomes cracked or chewed.
Can I put hot liquids in the Kelso Tumbler?
The Kelso Tumbler is designed for cold and room-temperature drinks. Hot liquids may cause pressure buildup in the sealed lid and could damage the silicone valve. Stick to water, juice, or other cold beverages for best performance.
