Hard water stains and mineral buildup: call a house cleaner — or fix it yourself

White, chalky deposits on faucets, showerheads, glass doors, and tile are caused by dissolved calcium and magnesium in hard water. Beyond looking unsightly, mineral buildup restricts water flow in fixtures, reduces water heater efficiency, and etches into glass surfaces permanently if left too long. A professional deep cleaning can remove existing buildup, and a plumber can install a water softener to prevent it from coming back.

How to fix hard water stains and mineral buildup

Hard water stains and mineral buildup

easy 20–60 min

Tools: spray bottle, microfibre cloths, old toothbrush, plastic scraper, squeegee · Materials: white vinegar, citric acid, baking soda, commercial limescale remover for heavy scale

Steps

  1. Spray glass doors and tiles with warm vinegar, wait 15 minutes, and wipe; for thick scale, lay vinegar-soaked paper towels on the surface for an hour.
  2. Make a paste of baking soda and a little water for stubborn spots, rub gently with a cloth, and rinse.
  3. Unscrew tap aerators and shower heads and soak them in vinegar or a citric-acid solution for an hour.
  4. For chrome, rinse and dry straight after — acid left on plating dulls it.
  5. Squeegee the glass after every shower; scale needs standing water to form.

Stop and call a pro if

  • the glass is etched (cloudy even when wet) — that is permanent, and replacement is the fix
  • scale is closing up the water heater or dishwasher as well — a water softener question
  • the surfaces are natural stone (marble, travertine) — acids etch them; use a pH-neutral stone cleaner
