Municipal tap water contains dissolved minerals like calcium, lime, and magnesium. When regular water evaporates from window glass, those minerals remain behind as cloudy white spots. Purified water systems filter out all dissolved solids. Because the water is completely pure, it acts as a dirt magnet and evaporates away without leaving spots or streaks.

Yes, professional washing removes fresh mineral deposits and water stains caused by lawn irrigation. Technicians use dedicated scrubbing pads and purified water to dissolve surface scale. If sprinkler water has baked into the glass over several seasons, light etching may remain, but a thorough wash noticeably improves clarity and stops further glass decay.

Most homes in the Orlando area benefit from exterior window cleaning every six months. Properties exposed to heavy pollen, coastal breezes, or constant irrigation overspray often need cleaning quarterly. Routine exterior washing prevents hard minerals from permanently etching into the glass and keeps natural daylight entering your living areas throughout the year.

Exterior window cleaning includes rinsing and wiping down exterior window sills and frames to clear away dirt, spider webs, and debris. Exterior screens are dusted and rinsed with low-pressure water. If screens require deep cleaning or interior track detailing, technicians review those options during the initial property estimate.

Homeowners do not need to be home while exterior windows are washed. Technicians only need an accessible exterior water connection, closed windows, and unlocked side yard gates. The crew completes the wash, inspects every glass panel, packs up the equipment, and calls you to confirm the job is complete.
