Care guide
Look after it, and it lasts for years.
Five minutes a week keeps a stainless steel flask clean, fresh and keeping heat like the day it arrived.
Before first use
Wash the flask, lid and seal in warm soapy water and rinse well. Fill it with boiling water, close it for ten minutes, then empty it. This clears any smell of the factory and warms the steel for its first tea.
Every day
- Pre-heat with boiling water (or pre-chill with iced water) for five minutes before filling.
- Fill close to the top: less air means less heat lost.
- Close the lid fully after each pour.
- Rinse it as soon as it is empty, before tea dries on.
Every week
Add two tablespoons of baking soda, fill with hot water, close and leave for 20 minutes to an hour, then brush and rinse. Take the lid apart and wash the seal. Let every part dry before reassembling. Our cleaning guide covers stains and smells in detail.
Never
- Use bleach, chlorine or steel wool.
- Put the flask in a dishwasher, microwave or freezer.
- Store it sealed while damp.
- Carry hot drinks in it with the lid half closed.
