Hard-water stain removal is restoration, not cleaning, and in Midland-Odessa it is one of the most-requested things we do. Midland-Odessa draws Colorado River Municipal Water District surface water from Lakes Ivie, Spence and Thomas, which Midland blends with its T-Bar and Paul Davis well fields, and every drop of that water that dries on glass leaves dissolved calcium and magnesium behind. Washing does not dissolve carbonate. That is why the same spots survive repeated cleanings and why homeowners conclude the glass is simply ruined. Usually it is not.
Quick answer
Hard water stains can be removed if treated within ~6 months. Older stains may have etched the glass and require professional cerium oxide polishing.
The checklist is the same everywhere. What is on your glass is not. These are the conditions that actually shape this job in Midland-Odessa. Each one is true here and false in plenty of other towns we serve.
Midland-Odessa is on Colorado River Municipal Water District surface water from Lakes Ivie, Spence and Thomas, which Midland blends with its T-Bar and Paul Davis well fields. West Texas water is hard, and this climate is built to evaporate it: low humidity, strong sun and steady wind. Sprinkler heads near the house, a hose rinse left to air-dry, and lawn irrigation that clips the lower panes all leave white mineral spots behind, and in this sun they bond to the glass within days instead of sitting loose on top. Caught in the first season they wash off with the right chemistry. Left for a few summers they etch, and etching is in the glass, not on it.
Mineral deposits sit on the glass surface at first and can be lifted completely. Left in place, calcium carbonate slowly etches into the silica itself, and at that point no chemistry brings it back. The surface is physically pitted. As a rough rule, deposits under about five years old restore fully, deposits past that improve substantially but not perfectly, and deposits allowed to build for a decade in high-UV sun are usually permanent. We test an inconspicuous section in Midland-Odessa homes before quoting, and we tell you which category you are in rather than taking the money and hoping.
The most expensive way to own hard water is to pay for restoration every spring because a sprinkler head still hits the same window. Before we leave a Midland-Odessa job we point out exactly which heads, drip emitters, or downspout splashes are putting mineral on your glass. Moving one sprinkler is a ten-minute fix that saves years of restoration cost, and we would rather tell you that than schedule you annually.
Diagnostic, we evaluate the staining to determine fresh-deposit vs. etched. Fresh deposits sit on the surface and feel slightly raised; etched glass is permanently roughened.
Chemical treatment for fresh deposits, acidic dissolver applied with controlled dwell time, then thoroughly rinsed. This works on stains < 6 months old.
Cerium oxide polishing for older deposits or light etching, graduated polishing pads with cerium oxide compound, machine-applied. This is slow, careful work, about 5-10 minutes per pane.
Severe-etching diagnosis, for glass that's been etched > 1 year, we honestly tell you whether polishing will work or whether replacement is more cost-effective. We'd rather tell you to replace one window than waste 4 hours of your money on glass we can't restore.
Sprinkler-overspray prevention recommendations: every job ends with practical advice on how to prevent recurrence: sprinkler-head adjustment, deflector caps, scheduled rinse-down with deionized water.
Tech walks the property, photographs every affected window, and rates each pane fresh / older / etched / unrecoverable. Customer sees the assessment in writing.
Hydrofluoric-substitute acidic dissolver applied carefully: controlled dwell time, neutralizing rinse, full water rinse. Repeated up to 3 times per pane if needed.
Graduated polishing pads (1500, 2000, 3000 grit) with cerium oxide compound. Slow, careful work. Restores gloss to the glass surface.
Standard window clean to remove all polishing residue. Final inspection from inside and out, with photos of before/after.
Recommendation on sprinkler adjustments, future cleaning frequency, and any glass that needs replacement rather than restoration.

Midland and Odessa is in the Permian Basin. Sonlight opens here Saturday, October 31, 2026. Glass in this part of Texas deals with spring wind and dust storms off open ground, hard water that dries fast in strong sun, and hail in the spring storm season.
The water here is hard, and wind, low humidity and strong sun dry it on glass almost immediately. Mineral spotting from sprinklers and hose rinses bonds within days. In its first season it comes off with mineral-removal chemistry; after a few summers it etches, and etched glass can only be restored or replaced. Moving the sprinkler head that put it there is half the fix.
Most of the time they come off. If the deposit is surface-bonded, generally under about five years of buildup, a controlled acidic restoration removes it completely and the glass returns to clear. Once the carbonate has etched into the silica, restoration improves the appearance but cannot make it perfect, and the honest options become glass polishing or replacement. We test before quoting so you know which one you have before you spend anything.
It is priced by the affected window rather than by the house, because usually only some elevations are affected. Light spotting is at the low end; multi-season buildup on a sprinkler-facing elevation is at the high end. We quote it separately from the wash so you can see exactly what the restoration portion costs and decide window by window.
Yes, if caught within ~6 months. Fresh deposits dissolve with the right acidic chemistry. Stains older than 12 months may have etched into the glass; cerium oxide polish can restore gloss for moderate etching, but severe etching is permanent.
Run your fingernail across the cloudy area. Fresh deposits feel slightly raised; etched glass feels smoother than the surrounding clear glass. If you can see the cloudy area is below the rest of the surface (a slight depression), that's etching.
Hard-water removal is an add-on to standard window cleaning, priced by the affected window because usually only some elevations are hit. Light spotting costs less than multi-season buildup, and severe etching that needs cerium oxide polish is priced per pane. You get the exact number before we start.
Sometimes, for very fresh stains less than 3 months old. Spray undiluted white vinegar, let it sit 5-10 minutes, scrub with a non-abrasive pad, rinse. For older or heavier deposits, you need a commercial mineral deposit remover or professional service.
