Hard water deposits on fixtures — Haarlem, Noord-Holland

White, chalky deposits on faucets, showerheads, and glass doors are caused by mineral-rich hard water. Over time the buildup restricts water flow, etches glass permanently, and dulls chrome and brushed-nickel finishes. Store-bought sprays treat surface film but can't dissolve deep mineral crusts around aerators and valve seats. A professional deep cleaning service uses commercial-grade acid-based descalers, soaks fixtures safely, and polishes surfaces back to their original finish without scratching.
