FIX GLASS WHERE THE SURFACE IS ETCH OR DISSOLVED MAKING IT APPEAR DULL
COMMON AREAS WHERE PROBLEM GLASS APPEARS

- construction sites
- sloped glazing – conservatory roofs, skylights, canopies
- buildings with difficult access for routine washing
- glazing exposed to run-off from concrete, bricks, mortar, stonework, lead flashing, silicone sealants
- glazing in polluted areas – city centres, industrial estates, near roadworks, coastal
- interior glass – shower enclosures, sandblasted glass, kitchen splashbacks
WHAT CAUSES PROBLEM GLASS?
The two biggest enemies of glass are moisture and alkalinity. Either individually or together, they can etch or dissolve the surface of glass, making it appear dull and sometimes white in appearance. Some dirt can damage the surface, and further harm can be caused in efforts to remove it.
Inorganic dirt bonds chemically to glass and is difficult, if not impossible, to remove using conventional cleaning methods. Inorganic dirt on exterior glass includes sea spray, industrial emissions, metal oxides from railways and construction materials such as cement dust and building run-off. For interior glass, examples are limescale from hard tap water, fingermarks and cooking oil vapours.
