Hard water stains appear as white chalky spots or a cloudy haze that does not wipe away with standard cleaning. They are caused by mineral deposits — primarily calcium and magnesium — left behind when water from irrigation systems or sprinklers evaporates on the glass.

We use professional-grade acidic mineral removers and mechanical polishing where required. Most stains are removed in one treatment. Severe etching may require multiple passes. We assess the glass before starting and advise on realistic expectations.
