Are you looking for a way to quickly warm up your favorite beverage while on the go? Or maybe you’re wondering if it’s even possible to microwave a Yeti? Well, you’ve come to the right place! In this article, we’ll discuss the ins and outs of microwaving a Yeti, so you can start enjoying your hot drinks without having to wait.


Yeti mugs are incredibly popular products for keeping drinks hot and cold. Many people want to know if it is safe and possible to use their Yeti in the microwave. In this guide, we provide information on the risks and benefits of microwaving a Yeti mug, as well as best practices for doing so safely.

We will cover the various types of mugs available, how microwaves can affect the container material, and things to consider before putting your mug in the microwave. Whether you’re looking to warm up your morning coffee or re-heat your dinner leftovers, this guide will provide you with all the information you need to use a yeti in your microwave safely and effectively.

What is a Yeti?

A Yeti is a vacuum-insulated product made by specialty outdoor equipment company, Yeti Coolers. They are often used to keep food or drinks cold for long periods of time or maintain a hot temperature for the same duration.

The most common type of Yeti products which can be found on the market today include:

  • Tumblers
  • Mugs
  • Ramblers

All of these items have been designed with double-wall vacuum insulation that helps maintain the preferred temperature of food and beverages far better than traditional plastic cups and thermos bottles. Furthermore, they contain a proprietary material known as kitchen-grade 18/8 stainless steel which adds extra durability and insulation to each piece. So while these products are not intended to be microwaved, they are made with premium materials that can still provide reliable temperature insulated results without relying on electrical methods such as microwaving.

Choosing the right vessel to keep your drinks hot can be a daunting task. Yeti tumblers, mugs and bottles are some of the popular choices available on the market that are designed to keep beverages at their desired temperatures for extended periods of time. Many people are curious as to whether or not these containers can safely go in the microwave.

The answer is no; both Yeti tumblers and Yeti cups should not be microwaved because this type of heating could affect their waterproofing capabilities and even melt certain elements of the container. Rather than using thermal radiation to heat, Yeti drinkware relies on direct contact with a source of heat such as hot tea, coffee or soup kept inside it or hot water poured in from outside. This type of insulation is effective over long periods because it keeps hot drinks from cooling quickly while avoiding any chance of melting plastic components by underestimating the heating time and temperature required.

If you choose to use a microwave, we recommend only microwaving non-metallic liquids, such as water and prefers other methods when attempting to warm liquid contents already inside the container.

Potential Risks of Microwaving a Yeti

As Yetis are not specifically designed for use in the microwave, there are some potential risks and safety concerns associated with microwaving them. For example, the internal insulation may contain metallic fibers which could cause sparks, potentially leading to a fire or other damage to the Yeti.

Additionally, heating drinks or other items in a Yeti for too long may cause the container to warp due to its material composition, leading to leaks and general deterioration of the products design properties.

With this in mind, it is important to always use caution when deciding whether or not you should heat up something in your Yeti versus using a microwave-safe container.

Alternatives to Microwaving a Yeti

Though it’s not recommended, microwaving a Yeti for reheating beverages or food can be possible in some circumstances. However, it’s important to be aware that this could cause damage to the cup and could interfere with its insulation properties. The following alternatives are recommended for safe, effective reheating.

  • Using a hot plate: Heat your Yeti on a hot plate that is not set too high in temperature. Heat liquids and food slowly until they reach the desired temperature.
  • Using boiling water: Place boiling water into your Yeti to help bring temperatures up faster and more evenly than directly on a stovetop or hot plate.
  • Using an oven: Use low temperatures measured in 50 degree increments and reheat liquids and food carefully until they reach the desired temperature. Monitor progress regularly with an oven thermometer meter gauge to ensure you don’t overheat your Yeti cup or burn any of its components.

Cleaning and Maintaining a Yeti

It is essential that you clean and maintain your Yeti properly. If done correctly, it will ensure the safe use of your Yeti and its effective performance. Regular cleaning and maintenance will help prolong the life of your Yeti.


Sometimes your Yeti might need a thorough cleaning if an internal piece needs to be replaced or if it has been exposed to any spills, dirt or grime. The best way to clean your Yeti is by handwashing with soap and water, never immersing the container itself in water nor putting it into the dishwasher. Instead fill the inner container with warm, soapy water and let it sit for 30 minutes so that any residue accumulates on the surface of the container. Use a bottle brush or soft cloth to scrub away any dirt and spillage before eventually rinsing off with hot water and leaving it out to air dry thoroughly overnight.


It’s important that you never put your Yeti in a microwave oven as microwaves can cause arcing or spark due to metals present in its plumbing system which could cause fire hazards. Your microwaves warranty may become void if you choose to ignore this instruction as well as safety instructions from manufacturers like yeti cooler products.


After researching this topic, it is clear that it is not safe to microwave a Yeti tumbler or any other type of Yeti product. While stainless steel is generally safe to put in the microwave, Yeti tumblers and other thermoses are insulated and sealed with a vacuum, which still generates enough heat when microwaved to potentially cause damage.

Other products such as canned food or soup with metal can also be dangerous when microwaved as they may get dangerously hot. Additionally, never microwave materials like glass, plastic wrap or paper.

With all of this being taken into account, it’s best to follow the product instructions when trying to determine if an item should be microwaved. When in doubt, refer to the manufacturer’s guidelines or contact their customer service team for advice before risking damaging your Yeti product and potentially causing any injuries.


FAQs regarding microwaving a Yeti product:

  1. Can I safely microwave my Yeti product?
    No, we do not recommend putting your Yeti product in the microwave. The insulation within your tumbler or bottle is made with metals that can be dangerous when exposed to heat and microwaves. The plastic components can also melt or become damaged when exposed to microwaving, creating an unsafe environment for you when using the products. If you’d like to warm up your drink, we suggest keeping the lid off and placing it on a container of hot water.
  2. Can I put my Yeti Rambler or Bottle in boiling water?
    No, we do not recommend immersing any Yeti product in boiling water as this may damage the insulation and lead to leaks or cracks in the material that could unsafely expose inner materials. If you’d like to warm up your drink, again, we suggest keeping the lid off and placing it on a container of hot water instead.
  3. Is there a way I can safely heat up my food in my Yeti Rambler?
    Yes! We recommend using any external heating device such as a stovetop to comfortably warm food inside your Rambler without risking damage due to microwaving or boiling.
