Specialty Treatment
Hard Water Stain Removal
Oklahoma's water is notoriously hard — loaded with calcium, magnesium, and mineral deposits that bond to glass over time. Regular window cleaning can't remove them. Our professional acid-based treatment dissolves mineral buildup and restores your glass to crystal clarity. If your windows look permanently foggy or etched, this is the service you need.
Why Choose Green for Hard Water Stain Removal
Our Process
A professional, step-by-step approach that delivers consistent results every time.
Assessment
We inspect the affected windows and assess the severity of the mineral buildup. Some stains are surface-level; others have etched into the glass. We'll tell you honestly what's achievable.
Standard Cleaning First
We clean the window thoroughly first to remove all loose dirt and debris. This ensures the treatment works directly on the mineral deposits.
Acid Treatment Application
We apply a professional-grade acid-based treatment to the affected areas. This dissolves calcium, lime, and mineral deposits that have bonded to the glass surface.
Agitation & Dwell Time
The treatment is gently agitated and allowed to dwell on the glass to fully break down the mineral bonds. Severe cases may require multiple applications.
Rinse & Polish
We thoroughly rinse the glass with pure deionized water and polish to a streak-free finish. The result is dramatically clearer glass.

Frequently Asked Questions
Can all hard water stains be removed?
Most surface-level mineral deposits can be fully removed. However, if the minerals have etched into the glass over many years, we can significantly improve clarity but may not achieve 100% restoration. We'll assess and give you an honest expectation before we start.
Why can't regular window cleaning remove hard water stains?
Regular cleaning removes dirt and loose debris. Hard water stains are mineral deposits (calcium, lime, silica) that have chemically bonded to the glass surface. They require an acid-based treatment to dissolve the mineral bonds.
Is the treatment safe for my window frames and seals?
Yes, when applied by a professional. We carefully apply the treatment only to the glass and rinse thoroughly. We avoid contact with frames, seals, and surrounding surfaces.
How do I prevent hard water stains from coming back?
The best prevention is our Rain Repellant Treatment, which creates a hydrophobic coating on your glass. Water beads and rolls off instead of evaporating and leaving mineral deposits. We recommend pairing hard water removal with the repellant treatment.
My windows look permanently foggy — can you fix that?
Possibly. Foggy-looking glass is often severe mineral buildup that can be treated. However, if the fogginess is inside a double-pane window (failed seal), that requires window replacement — not cleaning. We can tell the difference on inspection.
