When it comes to enjoying your favorite hot beverages or reheating leftovers, many people wonder about the safety and practicality of using their beloved Tervis cups in the microwave. Tervis is an iconic brand known for its durable, double-walled insulated drinkware, which keeps hot drinks hot and cold drinks cold. But can you microwave Tervis cups without any worry? Let’s dive deep into the world of Tervis cups, their materials, and how they interact with microwave ovens.
Understanding Tervis Cups: The Materials Behind the Brand
Tervis cups are made from high-quality materials designed to enhance user experience. Primarily, these cups are constructed from copolyester, which is a type of plastic known for its strength and durability. This durability is one reason why many users fall in love with their Tervis cups. But what does this mean for microwave use?
The Composition of Tervis Cups
Before we determine whether Tervis cups can be safely microwaved, let’s look into their components more closely:
- Copolyester: This is a BPA-free, clear plastic that is resistant to staining, odors, and heat.
- Insulation: The double-walled design enhances insulation, providing better temperature control.
- Lid and Straw: Many Tervis cups come with lids and straws, also made from safe, durable materials.
These materials are essential for the performance of Tervis cups, but they also dictate their limitations, especially concerning microwave heating.
Microwaving Tervis Cups: What You Need to Know
The direct answer to whether you can microwave Tervis cups is it depends on the type of Tervis cup you have. While most Tervis products are designed with safety in mind, certain restrictions apply.
Can You Microwave Standard Tervis Cups?
For standard Tervis cups, the consensus is that you should not microwave them. While copolyester is microwave-safe to some extent, the combination of heat and the double-walled design may result in uneven heating. It’s also important to note that over time, prolonged exposure to high temperatures can cause the material to degrade or warp, affecting the integrity of your drinkware.
Special Considerations for Tervis Tumblers
When it comes to Tervis tumblers, the situation is similar. Although the tumblers are built with robust materials, they are not specifically designed for microwave use. Here are a few reasons to avoid microwaving tumblers:
- Potential for Melting: The heat from a microwave can create hotspots, leading to melting or warping of the cup.
- Pressure Build-Up: If a lid is on the tumbler while microwaving, it can trap steam, creating dangerous pressure and potential spills or explosions when opened.
Exceptions to the Rule: Microwave-Safe Tervis Products
While many standard Tervis cups are not suitable for microwave use, some products in their line do carry microwave-safe labels. These labels indicate specific items that have been tested for microwave use and meet safety standards.
Identifying Microwave-Safe Tervis Cups
If you’re wondering whether your Tervis cup is safe for microwaving, check for one of the following indicators:
- Microwave-Safe Label: Look for a tag or imprint that states the cup is microwave safe.
- Product Specifications: Refer to the manufacturer’s guidelines provided on the Tervis website or packaging.
Usage Tips for Microwave-Safe Items
If you find a Tervis cup that is indeed microwave-safe, keep the following tips in mind for the best experience:
Follow Manufacturer Instructions
Always adhere to Tervis guidelines regarding heating times and temperatures. They may specify maximum time limits or temperatures to avoid damage.

On days when you crave hot beverages, a standard ceramic microwave-safe mug is a better alternative. You’ll avoid risking the integrity of your Tervis cup while still enjoying your favorite drinks.
Stovetop Heating
For items like soups or broths, consider using a stovetop. This method allows for more even heating and is less risky.
Caring for Your Tervis Cups
Maintaining your Tervis cups will ensure they last longer and perform optimally. Here are some care instructions that can extend the life of your drinkware:
Proper Washing Techniques
Always hand wash your Tervis cups using mild soap and warm water. Avoid using abrasive cleaners or scouring pads, which can scratch the surface.

Can I safely microwave Tervis cups?
Yes, it is generally safe to microwave Tervis cups that are labeled as such. Tervis manufactures many of their products using materials that can withstand microwave heating. However, it’s essential to check the bottom of your cup for any specific instructions or warnings regarding microwave use. If the cup does not have a microwave-safe designation, it’s best to avoid microwaving it.
When microwaving, you should also keep in mind that the contents inside the Tervis cup might heat unevenly. This uneven heating can cause hot spots, which may lead to spills or burns if you are not careful.

Microwaving non-microwave-safe plastics can lead to warping, melting, or even the release of harmful chemicals. To ensure your safety, consider transferring your beverage to a microwave-safe container before heating it up.
You can also contact Tervis customer service for further clarification about a specific product’s suitability for microwave use. They can provide detailed information about the materials and offer recommendations for safe use to prevent any potential damage to your cup and ensure your safety.
Can I microwave a Tervis cup with a metal decoration?
No, it is not safe to microwave Tervis cups that have metal decorations or components. Metals can cause sparks and fires in the microwave, which can damage both the cup and the appliance. If your Tervis cup includes metallic designs, it should be kept away from the microwave.
If you’re unsure whether your Tervis cup has metal components, check the description on the Tervis website or contact customer service for clarification. For heating beverages containing metal designs, it’s best to transfer the drink to a microwave-safe container without any metallic parts.
How can I clean my Tervis cup after microwaving?
Cleaning your Tervis cup after microwaving is relatively simple. Most Tervis cups are dishwasher safe, meaning you can place them directly on the top rack of your dishwasher for easy cleaning. If you prefer hand washing, you can use warm soapy water and a soft sponge to avoid scratching the surface.
For stubborn stains or odors, a mixture of baking soda and water can help restore the cup’s freshness. After scrubbing, rinse thoroughly to remove any residual soap or baking soda before drying. Avoid using bleach or cleaners that might damage the cup’s plastic, as this can lead to discoloration over time.
