Spotlight on limescale

Limescale is made up of calcium and magnesium. These minerals are present in Eau de Geneve and contribute to provide the necessary daily intake of minerals that are essentials for the growth and maintenance of your bone structure. Before arriving in your home, your drinking water has come a long journey through the soil, becoming enriched along the way with many trace elements and minerals. Calcium carbonate, otherwise known as limescale, is one of these.

Tip to get rid of limescale, use some household white vinegar, leave, and rinse with water.

Spotlight on chlorine

Chlorine is required to maintain water quality during transport in pipes to your home. Added to the drinking water during the treatment process at a very low dosage, it presents no danger to health.

Tip: allow the water to aerate in a decanter a few minutes before consumption, to eliminate any chlorine odor.
