What are water spots, and what causes them? 

Water spots refer to unsightly stains left behind when water evaporates from a surface. They can appear on various surfaces, including glass, metal, and plastic. Water spots occur when water droplets dry out and leave behind mineral deposits like calcium and magnesium. These minerals stick to the surface and become visible as white or grey marks.

The most common cause of water spots is hard water. Hard water contains high levels of dissolved minerals such as calcium and magnesium, which don’t evaporate with the water droplets leaving stains behind when they dry up. This is why you will often see these types of stains commonly around faucets with frequent exposure.

Other sources that could cause water spotting to include rainwater, dew, sprinklers used in gardening, ever-wet regions with high humidity levels, or coastal areas near saltwater bodies.
