Limescale is basically nature’s way of saying your water is hard. It’s just calcium and magnesium carbonates that precipitate out of the water when it gets hot. Think of it as the ghost of evaporated mineral water, haunting your plumbing.
The real kicker? It’s not just ugly. It makes your kettle take forever to boil, destroys your washing machine’s heating element, and leaves a gross film on your shower glass. We need to kick it out, and we need to do it with stuff you probably already have under your sink.
