Yeti Confetti: Different Cleaning Methods of Tumbler Cup & Lid

Insulated tumblers or as we are used to calling them, ‘Yeti cups’ are an essential part of our outdoor experience.

While others just like carrying hot coffee with them anywhere they go. But if you wanted to sip on wine during those boring work seminars or family dinners, Yeti has a Wine Tumbler that has your back.

In the past few months, it seems movement restrictions have gotten more relaxed day by day across continents.  As the pandemic slowly becomes more manageable, we can go out more, and it may be time to bring the tumblers and travel mugs out and about.

You’ll soon need hot coffee and cold drinks again. But here’s the issue, your Yeti cups need a good long rinse along with their lids, and you’re confused whether they are dishwasher-safe, whether you can shove a mug inside the microwave, how durable they are, etc.

Let’s dive into the specifics of all things Yeti cups.

So, Are Yeti Cups Dishwasher Safe?

In short, yes, Yeti can go in dishwasher. Although Yeti themselves advised against it in the past and encouraged manually washing them, recently, they have confirmed that all Yeti cups are dishwasher-safe.

Moreover, it was a popular myth in the past that dishwashing Yeti cups would result in irretrievable to their vacuum seals because of the high temperatures involved.

However, that is not the case, thanks to the double-layered vacuum insulation architecture of Yeti products. They are all made with robust 18/8 stainless steel that is very tolerable to high temperatures. Therefore, it is safe to pile up Yeti cups inside your dishwasher without worry.

How about Yeti Lids, Are They Dishwasher Safe?

Yeti maintains that their lids are dishwasher safe as well. The lids and seals are durable enough to go through dishwashing cycles. However, it is perhaps the wiser decision to wash the lids manually.

The rubber gasket that comes with every lid maintains the function of the entire cup, keeping it airtight. Any damage to the rubber gasket may result in malfunctioning drinkware as the whole.

The high temperatures inside a dishwasher may be enough to wear out the rubber gasket, especially after repeated washes. Moreover, washing the ramblers is quite simple whereas, washing the lids requires intricate attention. You need to ensure you’re reaching every nook and corner to clean all the deposits that have built up over time.

If you’re wondering how to clean Yeti cups and their lids without a dishwasher, here’s a detailed guideline to follow:

Washing the Yeti Cup and its Parts

To wash the cup:

  • Create a soapy solution of hot water and your regular mild dish soap
  • Soak the cup in the mixture and allow the grime to loosen up
  • Use a soft sponge to scrub the cup inside out carefully
  • Rinse the Yeti cup with clean water and let it air dry

To wash the lid and all its components:

Yeti cups come with different types of lids, and the most popular one is their MagSlider lid. The MagSlider lid consists of the lid itself, the rubber gasket, and the slider. We are going to remove all parts and clean them individually.

  • First, disassemble the rubber gasket and the slider-top
  • Now, soak all parts in a hot soapy water solution
  • Let the grease buildups breakdown
  • Use a toothbrush or a scrub to scrub through all the narrow areas carefully
  • Rinse with clean water and let them air dry

Can You Put Yeti Cups in the Microwave?

A big and bold NO; microwaving yeti cups is a bad idea because all Yeti drinkware includes mugs, ramblers, jugs, etc., are made from 18/8 stainless steel. As we know, steel, aluminum, and any such conductive metals are prone to radiation and can heat up excessively.

Microwaving Yeti drinkware can result in sparks, smoke, and even break out of flames inside the oven and therefore can cause dangerous accidents.

Besides, why microwave a Yeti cup anyway? These marvels of conductive metal are made to keep things hot or cold inside for hours on end. If you want to enjoy your hot coffee hours later than when you made it, just pour it directly from the kettle and into the Yeti cup and you don’t need a microwave.
