Cleaning The Thermos Flask: It’s That Easy

Thermos flask – cleaning is that easy

• Baking soda: Boil some hot water and add it to your thermos along with baking soda. Then close the pot and shake it a little. After the baking soda has been allowed to work for a while, dump out the dirty water and rinse the pot. The amount of baking powder and the exposure time depends heavily on the dirt. A tablespoon of baking powder is usually enough.
• Denture cleaner: Denture cleaner works just as well as baking soda. Dissolve one tablet of the cleaner in your thermos and leave it to work. Follow the manufacturer’s instructions. Then rinse the pot well. Depending on the degree of soiling, you may have to repeat the process.
• Tip: You can easily increase the cleaning effect by adding some rice as soon as you fill in the water. As soon as you shake the pot, the rice acts like fine sandpaper on the inside walls and helps with cleaning.

Thermos flask – what belongs in it and what doesn’t?

Now that you know the best tips to help you get the job done, here’s what you should and shouldn’t put in your thermos flask. You will also get a tip on how you can better avoid dirt on the inside:

• You can fill any hot or cold non-carbonated drink into your thermos flask. However, you should be careful with perishable products such as milk. It is better to drink your coffee with fresh milk, which you add directly when you pour it than with milk poured in in the morning. This can quickly produce unpleasant odors if kept warm for a long time.
• Cola or other strongly acidic drinks have no place in a thermos flask. They attack the seal on the closure due to their acidity and ensure that a lot of pressure is created inside due to the carbon dioxide. This can cause a thermos to leak.
• As soon as you have drunk the last coffee or tea from your thermos flask, you should rinse it with warm tap water. Pour in some water and shake your pitcher. This will prevent residue from settling. In this way, your thermos flask stays clean for a longer period of time and does not develop any unpleasant odors.
