How should I clean the flask?

Rinse before first use. Flask and cups are dishwasher‑safe (strap removed); lid must be hand‑washed. Leave lid off to air dry between uses.

How do I remove odours or stains?

Add one teaspoon of bicarbonate of soda to hot water, leave overnight (lid off), then rinse thoroughly. Alternatively, soak in a vinegar solution.

Is it microwave safe?

No — this flask must not be used in a microwave, as it is fully stainless steel and not microwave compatible.
