Hard-Water Stain Removal

When water hits exterior glass and evaporates, the minerals it carried remain behind. Over time and with repeated exposure, those minerals build into visible deposits — cloudy spots, white marks, and a rough texture you can sometimes feel with your fingertips. Sprinkler overspray is one of the most common sources.

Ordinary window cleaning removes dirt, dust, and fingerprints, but it typically doesn't remove mineral deposits that have bonded to the glass. Hard-water removal is a separate, more intensive process that targets bonded mineral deposits and helps improve cloudy, hazy glass.
