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,
adding 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 mi-
crowave oven, an oven or
freezer.
— Do not keep carbonated
(fizzy) drinks in the flask. The
build-up of pressure can make
the cork explode with consid-
erable force. The same thing
may happen if sugary drinks
in the flask are exposed to
heat, as heat sets the fermen-
tation 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 the
fermentation process in mo-
tion. 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.
