When sprinkler spots or mineral haze remain after a normal window clean, the glass may need a dedicated buffing process. Pro Exterior evaluates and polishes hard-water and mineral-deposit staining on residential and commercial windows. Clear scope: Hard-water and mineral-deposit buffing only. Pro Exterior does not provide window scratch removal. Cleaning versus restoration ## Why the cloudy pattern can remain after the dirt is gone. Standard window cleaning removes loose soil, salt film, pollen, fingerprints, and ordinary residue. Hard-water staining is different. Water evaporates while dissolved calcium, lime, and other minerals stay behind, gradually creating white dots, cloudy arcs, or a rough-looking film bonded to the glass. This is especially common where lawn sprinklers repeatedly strike lower windows, patio doors, pool-enclosure glass, or storefront panels. More ordinary cleaning does not necessarily solve it; the deposit and the condition of the glass need to be evaluated first. A careful restoration process ## Inspect. Test. Buff. Review. Window buffing is approached as specialty work because every stain and glass surface has a different history. 01 ### Identify the condition We distinguish surface soil from bonded mineral buildup, failed seals, scratches, and deeper glass damage. 02 ### Test a small area A controlled test helps show how much clarity can realistically return before a larger restoration is recommended. 03 ### Buff the affected glass The deposit is worked with a glass-appropriate polishing process rather than harsher routine cleaning. 04 ### Review the result We inspect the glass from multiple angles and explain any etching or permanent damage that remains visible. Common Treasure Coast conditions ## Where mineral staining tends to show up. Stuart & Palm City ### Irrigation overspray Repeated sprinkler contact often leaves fan-shaped spotting on first-floor windows near lawns, hedges, and driveway beds. Sewall’s Point ### Waterfront glass Salt film and mineral spotting can overlap on exposed French windows, patio doors, and glass near landscaped waterfront areas. Hutchinson Island ### Balcony and slider glass Coastal exposure, rinse water, and building irrigation can leave layered haze on sliders, rail glass, and lower exterior panes. Know the limit before the work ## Buffing is not scratch removal. A mineral deposit sits on or reacts with the glass surface. A scratch is a physical groove in the glass. The equipment, risk, and restoration method are different, so Pro Exterior does not offer scratch grinding or scratch removal.

Window buffing is a specialty glass-restoration step for hard-water stains and mineral deposits that remain after normal cleaning. The glass is evaluated and a small test area may be polished before the full scope is recommended. ### What causes hard-water stains on windows? Sprinkler overspray, irrigation systems, pool water, and repeated runoff can leave calcium and other dissolved minerals on glass. As the water evaporates, the minerals remain and may bond to the surface. ### Can every cloudy window be restored? No. Buffing can significantly improve many mineral-deposit stains, but deeply etched, damaged, or failed insulated glass may not return to perfect clarity. We explain the likely result before recommending the work. ### Does Pro Exterior remove scratches from windows? No. Pro Exterior does not offer window scratch removal. Our buffing service is specifically for hard-water staining and mineral-deposit buildup.
