Limescale and hard water stains are common issues in households, particularly in areas with hard water. These unsightly deposits are primarily composed of calcium carbonate, which precipitates out of hard water. Over time, these deposits can build up, leading to thick, stubborn stains that are difficult to remove. Understanding the nature of these stains is the first step in effectively combating them.

Limescale buildup occurs when water with high mineral content, particularly calcium and magnesium, evaporates and leaves behind solid deposits. This is a common problem in regions with hard water, where the mineral content is naturally higher. The constant flow and evaporation of water in toilets make them particularly susceptible to limescale accumulation.
