Daily exposure to harmful ultraviolet rays, misdirected sprinkler heads, pre-cast leaching and run-off, metal oxidation, glazing breakdown, acid rain, and other environmental pollutants can leave damaging deposits on glass and window frames. If addressed soon enough, many of these deposits can be removed with relative ease (usually by hand) and rather inexpensively as compared to the cost of an extensive glass restoration project. This is because the stains are on the surface of the glass. Left untreated, however, these deposits will eventually chemically bond with the glass, requiring removal of its top layer in order to restore the glass to an acceptable condition. This process (usually a combination of chemicals and high-speed buffers) is extremely labor intensive, and can be very expensive.
Glass Restoration is the process of restoring glass to its original pristine appearance by removing stains, corrosion, or etching that cannot be removed with regular window cleaning. Because glass is such a porous substance, it is extremely susceptible to mineral deposits. Unfortunately, apartments/building owners often underestimate the amount of regular maintenance required to maintain the original sparkle and shine of glass. The trend towards less frequent maintenance of the glass on many commercial buildings has, in many cases, resulted in extensive damage that is very expensive to repair or replace.
