YETI says its stainless steel tumblers are dishwasher safe. Remove the rubber gasket from the lid and wash it separately. It is stainless steel, so it does not go in the microwave.
The cup itself is simple. It is stainless steel and handles a dishwasher. The part that causes trouble is the lid, where a rubber gasket traps grime if you leave it in. YETI suggests taking it out and cleaning it on its own. The details for a particular product, such as a mug or a bottle with a different finish, can vary, so the care card that came with yours is the final word.
| Cup | Dishwasher safe, per YETI |
|---|---|
| Lid | Top rack is the safe choice |
| Lid gasket | Take it out and wash it separately, such as in the silverware basket |
| Hand washing | Hot soapy water works too, then dry well |
| Microwave | No. It is stainless steel |
How to wash a YETI Rambler
- Take the lid apart and pull the rubber gasket out of the lid.
- Put the cup and the lid on the dishwasher, with the lid on the top rack.
- Wash the gasket separately, in the silverware basket or by hand.
- Dry the parts fully before you reassemble the lid.
- Check the gasket seats properly, so the lid seals again.
What happens when you get it wrong
- Grime under the gasket. Left in place, it holds moisture and builds up, which causes the smell people complain about.
- Sparks. Stainless steel arcs in a microwave and can damage both the cup and the oven.
- A loose seal. A gasket that is not pushed back fully lets the drink leak.
Hand wash if you want to be gentle with the finish, using hot soapy water.
Heat the drink in a ceramic mug, then pour it into the cup.
