Looking after your flask
Now let's talk about cleaning ! 🧼
There are many different ways to clean a flask but one of the most effective is to use a bottle brush. It's easier to dislodge the dirt inside the flask if you add a few drops of liquid soap and wash in clean, warm water.
For a thorough clean, soak the product overnight in a solution of water and baking soda. It will then be in tip-top condition!
The second option is to put your flask in the dishwasher, if you have one.
Do not put the flask in the microwave or freezer, and do not expose it to a naked flame or any other heat source.
