Glass bottles and carafes are one of the most aesthetic and sustainable ways of storing and serving water and beverages. 

However, over time, they can develop cloudy spots, white residue, and stubborn stains that ruin the clean aesthetic.

What Causes Hard Water Stains on Glass Bottles & Carafes?

Hard water stains occur when water containing high levels of minerals, such as calcium and magnesium, evaporates from the surface of glass. As the water dries, these minerals are left behind, creating white, cloudy spots or a chalky residue.

Common causes of hard water stains include:

1. Rapid use of mineral-rich tap water

2. Leaving water in bottles continuously

3. Not whipping bottes and simply letting them air dry

4. Infrequent deep cleaning

5. Exposing it to hard water often

Over time, these mineral deposits can build up and become more difficult to remove.
