The following methods can be used instead of microwaving a Tervis product:

  • Boiling water – Fill a pot with water and bring it to a rolling boil over your stovetop. Insert your cup and let it sit in the boiling water for 2-3 minutes before removing with tongs and enjoying your beverage at desired temperature.
  • Stovetop warming – A medium setting on your stove top should be enough for this method; simply put your cold liquid into the container and heat slowly until desired temperature is reached, stirring intermittently along the way, as needed.
  • Heating Pad/Hot Water Bottle – Place your container onto a heating pad or hot water bottle that has been preheated on low heat setting; this will warm up your beverage slowly without risking an accidental boilover while allowing you to keep an eye on temperatures easily throughout the process.
