Plastics that aren’t microwave safe can warp, change shape, or even break apart under high heat. This not only ruins your tumbler but can also leave lingering chemicals found in some plastics.
Release of Harmful Chemicals
Certain plastics can leach chemicals when exposed to high temperatures. This can be concerning, especially if you frequently drink from your tumbler.
Burn Hazards
The design of Tervis tumblers means that while they keep drinks insulated, they can also cause a false sense of safety. You might assume the outer wall is cool enough to handle, but the inner temperature can be dangerously high.
Proper Care and Maintenance of Your Tervis Tumbler
To ensure that your Tervis tumbler remains in excellent condition, follow these care guidelines:
Cleaning
Tervis tumblers are dishwasher safe, but to extend their life, hand washing is often recommended. If using the dishwasher, place them on the top rack away from heating elements.

Can you microwave a Tervis tumbler?
Yes, you can microwave a Tervis tumbler, but with some important caveats. Tervis tumblers are generally made from durable, heat-resistant materials, which can withstand the microwaving process. However, it’s essential to check the specific product labeling or the manufacturer’s instructions to confirm that your tumbler is microwave-safe.
Keep in mind that while the tumbler itself may be safe to use in the microwave, the contents inside often vary. For example, liquids that are heated to high temperatures can create pressure, potentially causing splattering or spills. Always use caution and consider stirring or checking the temperature of the liquid before consuming.
What should you avoid microwaving in a Tervis tumbler?
When using a Tervis tumbler in the microwave, it’s best to avoid any materials that aren’t microwave-safe. For instance, lids with metal or non-microwave-safe materials should never be placed in the microwave, as they can cause sparks and damage to the appliance. Additionally, avoid using the tumbler for items that are known to heat unevenly, such as oils or certain foods.
Unsealed items should also be monitored closely. Foods that may bubble, splatter, or expand can create pressure that risks spilling or causing a mess within the microwave. It’s always a good idea to microwave liquids with the lid slightly off or ajar to allow steam to escape safely.
How should you clean a Tervis tumbler after microwaving?
Cleaning a Tervis tumbler after microwaving is straightforward, but it’s crucial to ensure that you don’t use abrasive materials that could damage the tumbler’s surface. It’s recommended to hand wash the tumbler with warm, soapy water using a soft sponge or cloth. This method effectively removes any residue without risking scratches.
