Particularly in regions with very calciferous water, lime deposits quickly form in kettles & Co. By means of a simple principle, this can be prevented at least in the kettle: Our limescale trap consists of a ring of stainless steel knitted wire. This gives it a very large surface area, thanks to which it is able to bind to itself the lime present in the water (which would otherwise be deposited on the wall of the pot). If the ring has become clogged with lime, it is made usable again by lightly tapping.
