Water Spot on Glass

A frustrating situation for both window cleaners and their customers are the unsightly spots that sometimes remain on the windows even after they have been professionally cleaned.  A proper explanation of what causes these spots and what is required to remove them will hopefully alleviate any unrealistic expectations.

A government sponsored study was conducted in the mid-eighties to determine what was causing irremovable spots on skyscraper windows.

The spots were occurring from a variety of sources and categorized as: Acid Rain, Hard Water (from sprinklers, building washing, previous window washing), and “Screen Staining” (the sun’s UV rays actually stain an imprint from the screen onto the glass).

These spots vary in severity and are classified as:

Cat 1 – Mild to moderate spotting from Acid Rain and/or Hard Water. These spots can likely be removed with Blue Ribbon Cleaning glass restoration process.

Cat 2 – Severe spots from Hard Water and/or Acid Rain/ Screen Staining. These spots can possibly be removed by glass restoration process, using Clear (Hydrofluoric Acid).  Then we will seal the glass with a safety sealer. (Care must be taken with the Acid cleaning process as it can occasionally “frost” glass, which would result in glass replacement.  It cannot be used on automotive, tinted, mirrored, self-cleaning (titanium coated), tempered or stained glass and should not contact non-glass surfaces.)

***EXTREME CARE MUST BE TAKEN WHEN USING ACID***Gloves, safety glasses, and face masks must be used to protect skin and proper ventilation is required.

Cat 3 – Permanent spots and staining
The only option is to replace the glass. If spots are removed before it gets to Cat 3 you can possibly prevent glass replacement
