Care and Use

There’s Over 100 Years of Expertise in every Thermos

Since 1904, Thermos® has been developing innovative, high performance consumer products using vacuum insulation technology. We pride ourselves on delivering quality products that stand the test of time. However, like most things in life, if they’re not looked after properly, they can start to look a little worse for wear. That’s why we decided to use all of our knowledge and experience to put together a handy guide full of useful advice, to ensure you and your Thermos® enjoy a long and healthy life together.


Whilst most of our products are suitable for use in a dishwasher on the top shelf, they do prefer a gentler approach. To ensure your Thermos remains in tip-top condition hand washing is recommended, as dishwashers use harsher detergents and hot water that may affect the appearance of your Thermos.


Wash all parts thoroughly before first use with warm soapy water, rinse and allow time to dry.


Use abrasive cleaners or cloths as they may dull the finish.

Use bleach or cleaners containing chlorine on any part of your Thermos.

Immerse or soak in water for prolonged periods of time, as residual contents may become trapped between product components.


We want you to think of your Thermos as your trusted companion – something you can always rely on to go anywhere and everywhere with you. But like any friend, if you want it to stick around, you need to treat it right.


Preheat or pre-chill the product just prior to use by filling with hot/cold water for maximum thermal efficiency – attach the lid and allow to stand for 5-10 mins.

Follow the instructions to seal your Thermos to ensure it remains leak proof.


Over fill the container – leave space at the top for the lid to avoid overflow.

Leave contents in the container for longer than 24 hours, wash as soon as possible after every use.


Okay we’re not trying to be the fun police here, all we ask is that you take care, apply some common sense and only use your Thermos for what it’s intended for – enjoying food and drink ‘on the go’.


Always test the temperature of your products before consuming.

Be careful when using the product with quick spoiling agents such as dairy – this can cause pressure inside the container to build.


Use the product in a microwave, conventional oven or any other heat source.

Use tools or devices to force the container open.

Use the container to store or carry carbonated drinks or dry ice.
