FAQ

Appliances — FAQ

How do I clean my thermos?

Use warm soapy water and a soft bottle brush to avoid scratching the interior. For stubborn stains, a mixture of baking soda and water works wonders.

Can I put milk in my thermal carafe?

It is generally not recommended as milk can spoil quickly if not kept at the right temperature. If you do, ensure you clean the carafe thoroughly immediately after use.

Are these kettles safe for international voltage?

Check the specifications of your specific kettle model. Some travel kettles are dual-voltage, while others require a converter for use abroad.

How long will my beverage stay hot?

Most high-quality vacuum-insulated bottles will keep liquids hot for at least 8 to 12 hours. Results vary based on the initial temperature and the environment.

Does the stainless steel affect the flavor?

High-grade 304 stainless steel is non-reactive and should not impart any metallic taste to your beverage. Always rinse thoroughly before the first use.

What is the benefit of a vacuum seal?

A vacuum seal removes air between the walls, preventing heat transfer. This keeps your hot drinks steaming and cold drinks icy for much longer than standard containers.
