Classic Insulated Drinkware Use & Care

Wash any new Tervis product before using it for the first time.
Tervis Classic Insulated drinkware was designed to survive normal use in the dishwasher. We suggest you use your dishwasher’s manufacturer’s settings and, when possible, use the top rack of the dishwasher. If our taller drinkware products do not fit on the top rack, try to place them away from the heating element on the bottom of the dishwasher.
Sunscreen, Stains, Discoloration and Haze
Coffee, tomato and citrus products may cause slight discoloration so you should always wash and rinse the product thoroughly after each use.
Some sunscreens have been found to fade or discolor our drinkware – as well as many other everyday plastic products. Aerosol sunscreens may do more damage to our products than creams or non-aerosol pump sprays. This does not affect the integrity of Tervis products or your ability to use them. Should contact occur, wash drinkware thoroughly using soap, cool water and wipe dry with a soft cloth immediately. Sunscreens containing TiO2 (Titanium Dioxide) and ZnO (Zinc Oxide) as the only active ingredients do not affect our drinkware.
If at any time you run your drinkware through the dishwasher and there is a residue or haze, we recommend hand washing with a mild detergent. If the haziness does not go away, try using a very small amount of baking soda and a soft, wet cloth.
Check for Microwave Safety on bottom of tumbler.
If there is no Microwave warning on the bottom, Tumblers and mugs (without lids) are microwave safe for up to 30 seconds at a time.
Microwave When Full
This warning means the Tumblers or decorations are made with materials that can be microwaved as long as they are full of liquid up to 1 inch from the top of the cup.
Do Not Microwave
This warning means the Tumblers or decorations have metallic elements in them and are not microwave-safe.
Tervis drinkware reduces sweat or condensation; it does not eliminate it. Sweating on the outside of the drinkware is affected by the temperature and humidity of the environment in which it is used.
Condensation should not regularly appear between the two walls. However, it can occasionally occur after the drinkware is washed in the dishwasher. Air sealed between the two layers of the cup provides the insulating barrier that keeps “hot things hot and cold things cold.” That air contains a trace of moisture, which sometimes condenses between the layers after washing. It will usually go away within 24 hours or, typically, less. If there is a significant amount of moisture pooling between the walls, there may be a faulty seal where the two pieces of drinkware come together, which is covered under our lifetime guarantee.
We do not recommend stacking our tumblers. Stacked tumblers can get stuck together just like glassware. If they do become stuck together, some customers have told us they put theirs in the freezer overnight, which allowed them to more easily pull them apart.
The water bottle is intended for cold non-carbonated drinks. Hot liquids and carbonated beverages generate pressure inside the water bottle that may cause it to leak.
If the water bottle is leaking, make sure that the gasket is correctly placed in the lid and that your water bottle lid is securely fastened to the water bottle.
The water bottle and lid are dishwasher safe, top rack only. Do not remove internal gasket (silicone ring inside lid) for normal cleaning.
Removal & reinsertion of gasket
To remove the gasket, unscrew lid from water bottle, open lid and pull back into a locked position. Repeatedly tap base of lid on flat surface until gasket comes loose.
To insert gasket, press firmly with finger until gasket is completely seated in groove.
Make sure the lid is perfectly aligned with the bottle screw thread before securely fastening it to the water bottle. This can be achieved by either lining up the lid latch to the emblem on front, or the ounces on back, depending on which way you prefer the emblem to be facing when drinking, then screwing the lid on tightly.
