How to use vacuum flask for the first time?

Many customers nowadays choose insulated flasks as their travel mates or to bring along to work. People pick vacuum bottles and flasks for a variety of reasons, including growing worries about pollution, the impact on health from chemicals in cheap plastic bottles, as well as the convenience of keeping a favorite drink at an optimal temperature. Further down, we will be looking closer at some simple steps on how to use a vacuum flask for the first time.

Check the user manual

The very first thing on “How to use vacuum flask for the first time” is to check the user’s manual of the new flask. We should be able to find important guidelines to follow for top performance and optimum satisfaction of the flask. The usage is often printed on the box or a piece of paper placed inside along with the flask.

The user's manual for Rang Dong’s vacuum flasks. The company is Vietnam’s leading manufacturer of vacuum flask products.

First-time users should pay attention to crucial information involving warnings, cautions, and cleaning tips. 

Users should note of the heat retention time of the flask. Usually, the “keeps hot things hot” line comes with an assumption that the flask is filled with liquid at maximum/minimum temperature and up to its full capacity. Therefore, during usage, the times of the lid opening or the beverage volume reduction would affect the overall heat retention.

First-time cleaning

After getting a new flask, we should clean it simply with water and detergent from inside out. It is recommended to use neutral detergent, otherwise, it could affect the surface of the stainless steel or its painting. This process could be repeated twice to three times if necessary.  

As soon as we rinse and empty the bottle, let’s turn the flask upside down or use a towel to remove any excess water, then let it sit on the counter or table to air dry completely. Voila, the vacuum flask is ready for use.

Regular maintenance

Just like any other products, vacuum flasks require regular maintenance and cleaning. The bottle design may make cleaning difficult sometimes. We should use a soft cloth or bottle brush cleaner. Please also don’t forget to use neutral detergent to minimize the impact on the stainless steel surface or the printing.

The inner surface of the flask is easy to get stained by drinks like coffee or tea. To get rid of those stains, simply fills the flask with a mixture of some baking soda, vinegar with hot water. Let it sit for about ten minutes and rinse the flask with water a few times till the vinegar smell is gone. 

Finally, our vacuum flask should always be stored at a clean and dry area, such as a cupboard.
