Take good care of your vacuum flask
Wash, rinse and dry the vacuum
flask before using it for the first
time. Always empty the vacuum flask
after use. Wash it by hand and add
bicarbonate of soda or washing-up
liquid to the water. Use a bottle brush
to make sure it is thoroughly clean
inside.
Good to know
• Pre-heating the flask with hot
water (or cooling it with cold
water) makes sure the contents
retain the desired temperature for
longer. Never use a vacuum flask
in a microwave oven, an oven or a
freezer.
• Not to be used on a hob, a hotplate
or any type of cooktop.
• Do not keep carbonated (fizzy)
drinks in the flask. The build-up
of pressure can make the cork
explode with considerable force.
The same thing may happen if
sugary drinks in the flask are
exposed to heat, since heat sets a
fermentation process in motion.
• If possible, avoid using the vacuum
flask for baby food and for drinks
made with hot milk. Bacteria can
develop rapidly in the heat and set
a fermentation process in motion.
If you do keep milk or baby food in
the flask, make sure this is only for
a short time and always clean the
flask carefully afterwards.
