Quick Answer

Yes, the Kelso Tumbler 2-Pack is dishwasher safe, but placing the lid on the top rack and using a gentle cycle helps preserve the silicone valve that prevents leaks.

Why Dishwasher Care Matters for the Kelso Tumbler

The Kelso Tumbler's leak-proof design relies on a built-in valve inside the silicone sipper spout. Over time, high heat or harsh detergents can weaken that valve, causing drips. A few simple adjustments keep your tumblers working like new.

How to Safely Clean Your Kelso Tumbler in the Dishwasher

  1. 1. Disassemble the lid: Remove the silicone sipper spout from the lid. Most Kelso lids allow you to push the spout out from the underside. Wash the lid, spout, and cup separately. Common mistake: washing the lid with the spout still in place can trap food and detergent, leading to odors and valve damage.
  2. 2. Load on the top rack only: Place the cup, lid, and spout on the top rack of the dishwasher. Keep them away from the heating element at the bottom. Checkpoint: if your dishwasher has a heated dry cycle, turn it off or use the air-dry setting to avoid warping the silicone.
  3. 3. Use a gentle cycle and mild detergent: Select the normal or light cycle with a standard dishwasher detergent. Avoid extra-hot sanitize cycles or bleach-based tablets. Common mistake: high heat from sanitize cycles can degrade the silicone valve, causing the tumbler to leak over time.
  4. 4. Air dry completely before reassembling: After the cycle finishes, let all parts air dry on a dish rack. Make sure the inside of the spout and the valve are fully dry. Checkpoint: reassembling while damp can trap moisture, leading to mold or a musty smell inside the spout.
  5. 5. Reattach the spout securely: Push the silicone spout back into the lid until it snaps into place. Give it a gentle tug to confirm it's seated firmly. Common mistake: a loose spout breaks the seal, so the tumbler may leak even though the lid is closed properly.
