Clean thermos with liquid soda

Today I tried my soda liquid cleaner. My thermos thanked me.

This is how it works: Add a dash of soda to the pot and fill with hot water. Let something stand and you marvel everything like new. Possibly. clean with a bottle brush or cloth. Rinse thoroughly, perfect!

Marmot: Just put two Zewa cloths in the pot and half full hot water, close the pot and then shake vigorously, open the pot again, pour out water - the Zewatücher come out with the water - and behold, the pot is sparkling clean without any additional cleaning agents! The bottle brush is no longer needed! A cloth is then possibly still attached to wipe the pot outside, so it looks fresh and clean again! As simple as that!!
