The thermal jugs were a real sensation many years ago. Today you can see them in every kitchen and you would definitely not want to do without them. Do you actually know that you should clean a thermos flask? In a previous article, we reported extensively on the damage that limestone can cause. Limescale deposits not only damage the device itself. The small particles of limestone get into our bodies through the water and that’s really not healthy. So that we don’t pollute the groundwater with the many chemicals, we will again resort to household remedies today. We can generally recommend the home remedies as universal cleaners.

They clean and leave a totally fresh scent behind. Especially in the kitchen, we would always prefer household products as cleaners. We drink fresh water from the water can and it would be good if the water was clean too.

Cleaning the thermos – what should you always pay attention to?

Everyone now relies on sustainable kitchenware and appliances that make our lives and kitchen work easier every day. A stainless steel kettle looks great when you unpack it and put it in the kitchen corner.



Even new devices have a tough layer of limestone when they are purchased, which should be removed immediately. Unfortunately, our tap water contains a large amount of limestone. Over time, the material builds up in the pipe and also on the bottom of your kettle. They simply want to boil water for tea and are horrified to discover that strange particles are floating in the boiling water. It’s not appetizing at all, so you should clean your thermos in this case.
