Coffee without lime scale!
Coffee is so good! … but the lime scale that builds up in the kettle is disgusting! To solve this problem without resorting to chemical products (which for certain do no good to either your health or the taste of your coffee) there is a simple and certainly more natural way.
Fill the espresso maker with water and vinegar in equal parts and add a pinch of finely-ground salt, put it on the fire and let all the water filter through. Rinse carefully. The lime scale disappears!
