Hard Water Stain Removal
in Dacula, GA
Those white, cloudy spots on your glass aren't going away with regular cleaning. Mineral deposits from sprinklers, well water, and irrigation bond to the glass and need specialized treatment to remove.
You've probably seen them - those white, cloudy, spotty marks on your windows that won't come off no matter how hard you scrub. You spray glass cleaner, wipe with a paper towel, try vinegar, try everything you can think of, and the spots just stay there. They look like someone splashed milk on the glass and let it dry. Those are hard water stains, and they're one of the most common window problems we see in Dacula, Georgia.
At Kidd's ProWash, we remove hard water stains from windows all across Gwinnett County. It's not a regular window cleaning job - it takes specialized compounds, the right technique, and a good amount of patience. Regular glass cleaner won't touch these stains because they're not sitting on the surface of the glass. They're bonded to it. The minerals have actually etched into the glass over time, and they need a specific process to break them loose.
What Causes Hard Water Stains on Windows?
Hard water stains come from mineral-rich water drying on the glass surface. The water evaporates, but the minerals - calcium, magnesium, silica, and lime - stay behind. Each time water hits the glass and dries, another thin layer of mineral deposits gets added. Over weeks and months, those layers build up into visible white or cloudy spots that are physically bonded to the glass.
Sprinkler Systems
The #1 cause in Dacula. Irrigation heads that spray too close to the house send mineral-rich water onto windows every time they run, adding deposits layer by layer.
Well Water
Homes around Auburn, past Harbins Road, and toward Winder Highway run on well water high in iron and calcium. Any contact with windows - hose, pressure washer, rain runoff - leaves stains.
Construction Runoff
With new development around Dacula, Hamilton Mill, and Buford, water from fresh concrete and mortar is loaded with minerals and lime, causing some of the worst staining.
Why Regular Cleaning Won't Work
This is the thing that frustrates most homeowners. You hire a window cleaner or spend a weekend washing windows yourself, and the spots are still there. The glass looks a little better where the regular dirt came off, but the mineral stains are exactly the same. That's because standard window cleaning products and techniques are designed to remove surface dirt - pollen, dust, grime, fingerprints. They dissolve and wipe away organic material.
Hard water stains are inorganic minerals that have chemically bonded to the glass. Glass is a mineral itself, and when calcium and silica from hard water meet the silicon dioxide in glass, they form a bond. Think of it like calcium scale building up inside a water heater - it's the same kind of mineral deposit, just on the outside of your windows instead of inside a pipe.
Vinegar, rubbing alcohol, and standard glass cleaners are too weak to break that bond. You need compounds specifically designed to dissolve mineral deposits from glass surfaces. That's what we use, and that's why the results look so different from regular cleaning.
Hard water stains aren't just sitting on the surface - they're chemically bonded to the glass at a molecular level. That's why vinegar and glass cleaner don't work. Professional-grade mineral-dissolving compounds are the only way to break that bond.
Our Hard Water Stain Removal Process
This isn't a quick wipe-down. It's a glass restoration process that takes the right products, the right technique, and patience.
Evaluate Severity
We assess the staining - light stains from a few months respond quickly, while years of sprinkler exposure take more time and product. We give you an honest assessment before starting.
Apply Mineral-Dissolving Compound
We apply a professional-grade product formulated specifically for glass restoration - not something from a hardware store. It breaks the bond between minerals and the glass surface.
Agitate & Polish
We work section by section using fine-grade pads and controlled pressure. For heavy staining, this process may be repeated two or three times on the same pane.
Final Window Cleaning
Once deposits are removed, we clean the entire window with our standard process for a streak-free finish. Glass that looked permanently cloudy comes back to crystal clear.
Preventing Hard Water Stains from Coming Back
Removing the stains is half the battle. The other half is keeping them from coming back. If the source of the hard water is still hitting your windows, the stains will return. Here are the main things we recommend to our customers around Dacula and Gwinnett County.
Prevention Tips
Hard Water Stains vs. Other Window Problems
Not every spot or mark on your windows is a hard water stain. Sometimes what people think are mineral deposits are actually something else entirely. Here's how to tell the difference.
Hard Water Stains
White, cloudy, or chalky. Usually concentrated near sprinkler zones, below roof drip lines, or around garden hose areas. Won't wipe off with glass cleaner.
Rust & Oxidation
Orange or brown stains from metal window frames, screens, or nearby fixtures rusting. Our rust removal service handles that type of staining.
Foggy Double-Pane
A seal failure between two panes traps moisture inside. No cleaning from inside or outside will fix it - the window unit itself needs replacement.
Pollen Film
Yellow-green and wipes off easily with a damp cloth. If it comes off with a simple wipe, it's not a hard water stain. Pair screen cleaning with regular window cleaning for control.
Common Areas Where We See Hard Water Staining
In neighborhoods around Dacula, the most common spots for hard water staining are first-floor windows near landscaping beds with sprinkler systems. Homes in Hamilton Mill, along Fence Road, and in the subdivisions around Lawrenceville tend to have well-maintained irrigation, which is great for the lawn but tough on the windows.
Glass shower doors inside the house are another common spot, though that's a different service. For exterior windows, we also see staining on glass near swimming pools - the splash water and the chemicals in pool water leave mineral deposits over time. Large windows and glass doors facing the backyard in homes around Buford, Suwanee, and Duluth are frequent candidates for this service.
Storefront windows on commercial buildings get hard water staining too, especially ground-floor windows near parking lot sprinkler systems or where landscaping crews water plants close to the building. We handle those for business owners across Gwinnett County.
Frequently Asked Questions
It depends on the number of windows affected and the severity of the staining. Light staining costs less because it takes less time and product. Heavy staining that has been building for years takes more work. We give free quotes and will always be upfront about what the job involves.
If left long enough, yes. Mineral deposits can etch into the surface of the glass to the point where even removing the deposits leaves a faint mark. That's why we recommend addressing hard water stains sooner rather than later. The longer they sit, the harder and more expensive they are to remove.
If the source of the hard water is still hitting your windows, they will eventually return. We always recommend adjusting sprinkler heads and addressing the water source as part of a long-term solution. Regular window cleaning also catches new deposits early before they bond to the glass.
It depends on the severity. A few lightly stained windows might take an hour. A full house with heavy staining on multiple windows could take half a day or more. We give you a time estimate along with your quote so you know what to expect.
Yes, completely. Regular window cleaning removes surface dirt, dust, and pollen. Hard water stain removal is a restoration process that uses specialized compounds to dissolve mineral bonds on the glass. It's a more involved process and priced accordingly.
