LifestyleCleaningBrown stains in your toilet bowl are likely limescale, not dirt – and bleach won't shift them.08:01, 12 Jul 2026Brown marks inside a toilet bowl are often mistaken for staining from everyday use, but they are far more likely to be caused by limescale — a natural mineral deposit left behind by the water itself.
