The term "hard water" pops up in various contexts, from plumbing discussions to the world of brewing. But what exactly does it mean? Essentially, hard water refers to water with a high mineral content, primarily calcium and magnesium. These minerals, dissolved from rocks and soil, are not harmful to our health, but their presence can impact our daily lives in a variety of ways.
Think of hard water as a "hold" on your water's properties. It can "hold" onto soap, making it less effective for cleaning and leaving behind a residue. This "hold" can also manifest as scaling in pipes, appliances, and even kettles, potentially reducing their efficiency or causing damage.
Here's a breakdown of some of the common issues associated with hard water:
