Can all hard water stains be removed?

Most light to moderate stains can be completely removed. Severe etching may not fully disappear but will improve noticeably.

What causes hard water stains?

Minerals from sprinklers, groundwater, and rain drying on your windows.

Will this damage my glass?

No — we use safe, controlled tools and products designed for glass.

How long does the process take?

Most treatments take 30–90 minutes depending on severity and number of windows.

Does this include a full window cleaning afterward?

Yes — every hard water stain removal service includes a complete exterior window cleaning.

Why Hard Water Stains Happen

Hard water stains form when mineral-rich water dries on your glass. In Florida, this happens frequently due to:

Lawn Sprinkler Overspray
Coastal Salty Air
Mineral Heavy Groundwater
Frequent Rain
Humidity & Evaporation

Over time, these minerals bond to the glass and become difficult — sometimes impossible — to remove with standard cleaning. Professional hard water stain removal uses specialized tools designed to break down deposits safely.

Some severe hard water stains may permanently etch the glass. In these cases, professional treatment can significantly improve clarity but may not fully restore the window to like-new condition. We’ll always provide an honest assessment.
