Are Yetis Microwave Safe? (The Real Truth)

Yetis are now the best choice for maintaining hot and cold drinks in their original states for extended periods of time. In fact, from workplaces to classrooms to malls and anywhere else yetis are a part of the scene.

These nicely padded cups may be seen poking out of backpacks, trolleys, and palms of all styles, walks of life, and color variations.

Yeti has created a big reputation for itself by producing long-lasting, high-quality, and visually appealing insulated drinking containers. At the same time, a yeti cup may cost roughly $35, and occasionally as much as $50.

It’s endless as to what you can do with these cups!

So, perhaps you have a Yeti mug, tumbler, or any other yeti-ware and want to know if it can be microwaved.

Fortunately, your fingers have not scrolled here in vain.

As a Yeti lover and daily user, I’ve got the down-low you need.

Let’s get this yeti party started!

Can you microwave a yeti?

No, it is not advised to microwave a yeti. For the sake of your safety and the operational sustainability of your microwave, Yeti beverage containers should not be microwaved. The 18/8 kitchen-grade stainless steel liquid carrier conducts electricity, posing a fire danger.

Therefore it is not advised as microwaving your Yeti may reduce its longevity and violate the product’s assurance agreement.

A friend of mine and I had a recent debate as it relates to this topic. She argued that at such a high pricing point and hype surrounding yeti products…

After all, It ought to be able to face off with the big bad microwave?

Nope, not exactly!

To settle the debate, I spoke with a Yeti agent to find out what the brand would have to say. According to the contact center agent, putting a Yeti in a microwave is risky and therefore extremely ill-advised.

That is a clear response from Yeti…

No, you cannot and should not microwave your yeti drinkware!

This led me to do further research so let’s discuss.

Why you can not microwave a Yeti?

Stainless steel is used to manufacture Yeti cups. Stainless steel, like other metals, conducts electricity. This makes it an incompatible companion to be used in the microwave.

To avoid venturing into too many of the technical aspects.

Microwaves function by delivering pulses of energy throughout an item, which then accelerates the vibration of the particles within it.

As all the particles proceed to vibrate at higher rates, friction is created. The friction is then transformed to heat thereby, raising the temperature of the materials within.

One issue regarding microwaving your Yeti would be that the material it is composed of will not enable energy pulses to adequately flow through it. Alternatively, stainless steel absorbs the energy until the atomic composition can no longer retain it.

At which point the surplus energy is expelled as warmth, noise, and a bit of spark.

Such sparking and warmth may start a fire, burn people, and inflict a variety of other serious injuries.

Additionally, placing something that is metal inside a microwave would have this consequence.

So this outcome isn’t unique to just Yeti cups.

It has long been recognized that metal can’t be properly microwaved without any safety alarms blaring, and Yeti mugs are no different.

What would happen if I microwave a Yeti?

As aforementioned, heating a Yeti will lead to excess heat accumulation. This will ultimately manifest as sparking, smoke, and maybe fire within your microwave.

This act is not only hazardous, but it is also highly doubtful to warm the contents within the Yeti in any way.

The stainless steel frame of a Yeti will insulate anything that is within, from the microwave’s radiation. It does this by obstructing and soaking up the energy given off from the microwave.

Simply put, the waves won’t be able to start heating the fluid inside the Yeti if they can’t catch it.

Hence the final outcome is a major hassle just for a lackluster beverage. It’s safest not to put your Yeti in the microwave unless you can perceive how long it’s going to take for fireworks to erupt.

This is not the 4th of July fireworks you want!

It implies you’re threatening a home fire to reheat a beverage utilizing a technique that won’t provide a hot beverage in the first place.

All in all, if you’re fortunate and no fireworks are created from microwaving your Yeti container, you’ll still wind up with a lukewarm beverage and a couple of minutes of lost time.

How to Microwave the Liquid in a Yeti

Yeti drinkables are wonderful for maintaining hot beverages. However, sometimes you end up leaving your beverage out for a prolonged period and it requires to be reheated.

So, what is the best method for reheating the components within your Yeti cup?

Firstly, in a microwavable vessel, reheat your favorite beverage. Afterward, load it into the Yeti.

The Yeti will keep it warm for around five to six hours, and thankfully you won’t have to worry about your home going up in flames.

Yetis are an excellent method to preserve warm drinks for later consumption while maintaining a freshly-brewed flavor.

Does Microwaving a Yeti Shorten Its Lifespan?

Whereas experts seriously discourage microwaving a Yeti due to serious potential hazards.

What happens if you do decide to do it?

Can it destroy your high-priced drink-ware?

Yeti mugs are composed of high-quality 18/8 stainless steel which prevents corrosion and denting. Nonetheless, if the stainless steel is warmed in the microwave its movable atoms will produce electricity.

Since heat renders metal highly pliable, it might lead the metal inside your Yeti to corrode bit by bit.

Unfortunately, if the cup is damaged in some sense, air might break free and the product’s prolonged heating and cooling capabilities will surely be compromised.

The possibility of leakage is also very likely and you would need to wave goodbye to your warranty!

How to preserve the longevity of a Yeti?

Assuming you take proper care of your Yeti cup as well as observe the vendor’s up-keeping instructions.

Your Yeti drinkware will endure beyond a good couple of years.

Yetis, on average, survive roughly 5 years when used habitually. That’s maybe up to 5 times weekly.

With that said, you can keep the authenticity of your cup by taking a couple of actions.

To maintain your Yeti in top shape, follow these instructions:

  • It should not be used in a microwave, cooker, or just about any hot equipment.
  • After each usage, be sure to wash it.

It may be cleaned with Yeti cleansing pellets as well as manually, using a bit of liquid detergent and warm water.

  • Prior to actually washing, remove any covers, rubber fittings, and bottle tops.
  • Allow no more than a couple of days for any liquid to remain within the Yeti.

Certain Yeti containers have three-year guarantees, but many may carry five-year contracts. It’s normally a 21-day wait for resolutions. Plus, your Yeti would have had to come in from a verified supplier.

So secure that receipt!

Because verification of payment displaying an accurate date will be asked for.


Can you microwave a tumbler?

No, yeti tumblers are not microwave safe so they should not be placed in the microwave. If you want to heat up your beverage, we recommend using a stove top or other methods.

Can you microwave insulated paper cups

No, paper cups or insulated cups are not meant to withstand the intense heat of a microwave and should not be placed in a microwave.

How long does yeti keep drinks hot?

Yeti tumblers keep drinks hot for a long time about 4 and a half hours on average. They are made with double-wall vacuum insulation so the heat stays in and the cold stays out.

Let’s Recap

Sadly, using a Yeti inside the microwave is unsafe as well as inefficient for heating your beverages.

On the contrary, the infamous Yeti brand has a well-deserved repute for manufacturing awesome devices. Yeti is known to retain your steaming drinks for hours regardless of the external atmosphere.

As a result, people might not have to reheat their latte or any other hot liquids too frequently.

If you do need to warm your drink, I suggest you microwave your beverage in some kind of microwavable vessel beforehand, then put it in a Yeti for the best thermal retention.

Now that you know this, be sure to maintain a safe distance between your Yeti and microwave.
