Hard water & mineral stains

Hard water and mineral stain removal

White spotting on glass, crusty scale on pool tile and chalky deposits on masonry are minerals left behind by evaporating water. We dissolve them instead of scrubbing them, so the finish underneath stays intact.

Where mineral stains show up

Florida water is hard, and every sprinkler cycle, pool splash-out and afternoon shower leaves a thin layer of calcium and magnesium behind when it dries. Over time that builds into spots on windows and glass railings, a white line at the waterline of pool tile, and crust on fountains, fixtures and masonry.

  • Windows & glass doors
  • Glass railings
  • Pool tile waterlines
  • Fountains & fixtures
  • Brick & masonry

How we restore it

  • Diagnose. We confirm the deposit is mineral and not etching, which no cleaning can reverse.
  • Dissolve. A treatment matched to the surface breaks the mineral bond, so we don't need abrasive pads that scratch glass and tile.
  • Rinse and protect. Where the surface allows it, we apply surface protection so new spots bead off instead of baking on.
Glass that has been spotted for years may be permanently etched. We'll test a small area during your free demonstration and tell you honestly what can come back before you pay for anything.

Pricing

Mineral stain removal is priced on site after a free demonstration, by the area and how heavy the buildup is. It can be added to any preservation plan so glass and tile stay clear between visits.

Questions about hard water & mineral stains

Can hard water spots be removed from windows?

Usually, yes, if the glass isn't etched. We test a small spot first and show you the result.

Will you scratch my glass or tile?

We don't expect to. We dissolve minerals instead of scrubbing with abrasives, and we test a small spot first.

How do I keep spots from coming back?

Aim sprinklers away from glass, and add protection plus regular visits through a preservation plan.
