FAQ:
- How do you know if a vacuum flask is good?
Not all vacuum flasks are created equal. You’ll want to take these factors Into account when shopping for a long-lasting flask.
Material
Always look for a vacuum flask that is made from stainless steel, preferably the one of 304 grade. This type of material is not only known for its durability but also offers excellent corrosion resistance as well as hot/cold retention.
Lid
Vacuum flasks are mostly used for storing hot/cold liquids or food. This is why the lid has to be secure. Find the one that has a leakproof lid with a silicone gasket or valve, both of which help to prevent the contents of your flask from leaking.
- Why can a vacuum flask keep drinks cold as well as hot?
Ever wonder how is it possible that a vacuum flask can retain the temperature of your hot or cold drinks? The answer lies in its double-walled stainless steel design that has a vacuum sleeve. It keeps liquids/foods hot or cold using three layers of protection (inner, vacuum & outer).
The vacuum between the two layers prevents heat from escaping the flask so your drink/food can stay hot for several hours. The same principle also applies to cold contents.
- How to clean a thermos flask
When comes to proper cleaning of a thermos flask to prevent an unpleasant or musky smell, one of the most effective cleaning methods is using baking soda and vinegar. Simply pour 1/2 cup distilled white vinegar and 1 tablespoon of baking soda into your flask.
Give it a shake and wait until the frothing reaction gradually wears off before you start filling the flask full with hot water. Leave it for a few minutes to allow the mixture to dissolve the stains while killing the germs within.
Then, grab a bottle brush and give it a good scrub around the inside of the flask as well as the bottom. Once complete, empty the thermos flask and rinse thoroughly to wash off not only the smell but also the remaining residue of the baking soda-vinegar mixture. Lastly, wipe the thermos flask with a clean cloth and leave it to air-dry.
