From pause tea to tea break, your kettle made more and more gray mine.
The deposits of tartar and black spots that are not very sumptuous which settle over time at the bottom of the apparatus increase its electricity consumption.
This is due to the reaction of the limestone in the water with the heat produced by the resistance.
Your kettle is therefore its ideal target.
To remedy this, no need to look for a costly antitarte in drugstore, instead opt for a half-bottle of Coca.
Pour a little at the bottom of the kettle.
Boil the liquid.
Throw away the hot coca.
Rinse the bottom of the kettle.
Repeat this until the black traces disappear completely.
