Use & Care

Keeping your Tervis product looking shiny and new is easy with a little love and a few helpful tips and suggestions.

Wash any new Tervis product before using it for the first time.

Dishwasher Safe

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.

Microwave Safe

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.

Water Bottle Use & Care

Make sure the lid is screwed on completely by aligning the indicators on lid and tumbler.

My First Tervis™ sippy cup is intended for non-carbonated drinks such as water, milk and pulp-free juice. Carbonated beverages can generate pressure inside the My First Tervis™ sippy cup and may cause it to leak. Carbonated or pulpy beverages may impede performance of the lid valve.

My First Tervis™ sippy cup can hold hot liquids, but we do not recommend microwaving liquid as it could burn your child. We recommend testing liquid temperature before giving to child.

Sippy Cup Use & Care

Do not place in dishwasher. Only use mild dish detergent and a non-abrasive sponge or cloth. Rinse with water and towel dry.

Do not store near heat sources, including stovetop, oven, radiator, heat vents or leave outdoors for an extended period of time. Exposure to excessive heat may damage the ice bucket.

Do not place in microwave.

Wash any new Tervis product before using it for the first time.

Not Dishwasher Safe

Never put your Stainless Steel Cup in a dishwasher, microwave, stove or freezer as harsh temperatures could disable the insulation properties.


Never use bleach- or chlorine-based cleaners to wash your Stainless Steel Cup.

Preserve Printed Decoration

Do not soak Stainless Steel product. Do not use abrasive sponges or scouring pads when cleaning as they could scratch the steel and Design by Tervis. We recommend a good-old fashioned soft sponge, mild dish detergent and a little elbow grease.

Do NOT microwave Stainless Steel products.

It is a safety hazard to place metal in a microwave. Never put your Stainless Steel product in a microwave.

Never scrape the ceramic coating and do not continue use if coating is damaged.

Soak inside of tumbler with warm water and baking soda to remove difficult stains.

Store with the lid removed to allow parts to fully dry.

All accessories (except straws) are dishwasher safe, top rack only. Accessories are not covered by a guarantee.

The size of the cup is noted on the bottom side of the item, and the lid size is noted on the underside of the lid. If you have a 16oz tumbler, you want to be sure the lid also says 16oz. We designed our mug to fit the 24oz tumbler lid. The water bottle lid and sippy cup lid are both threaded and are made to be used only on the water bottle and My First Tervis™ sippy cup respectively.

Travel Lids

Travel lid sliders can be removed by pinching the tabs on the bottom of the lid prior to washing.

Water Bottle Lids, 17oz Lids, Hammer Lids and Slider Lids

For thorough cleaning, remove the gasket from the lid. Hand wash and dry each component separately. Be sure to re-install the gasket prior to use. Failure to properly re-install the gasket may cause leaking.

Make sure that the handle is securely attached to your tumbler before use.

To ensure spill-free mixing, hold the shaker cap firmly in place while shaking beverage. If the lid is not held in place, it may become loose or dislodge during shaking causing spills.

Straws should be cleaned by hand – we’ve been told a pipe cleaner helps to get the tough-to-reach places, followed by a warm rinse.
