Surface contamination on glass, either through environmental conditions or its proximity to other materials, can cause the glass to lose its transparency. Chicago Glass is able to remove these tough deposits on the glass, which are not able to be removed with general cleaning products. Below are some Common Types of Surface Contamination found on glass.
Lime scale stains and run-off - Occurring when rainwater flows over mortar, green concrete and some types of stonework onto a glass surface, depositing insoluble salts of calcium crystallize which become chemically bound to the glass.
Metal Staining and run-off - Weathered metal releases oxides over time, and these can become adhered to the glass surface should rainwater flow across the metal onto the glass surface. The staining can be seen as white or grey streaks across the glass.
Traffic Film - Seen typically as a blue haze on the glass, this surface contamination is a combination of soot, airborne dust particles and partially burnt vehicle fuels that react with the surface of the glass resulting in a chemical bond.
Train Braking Stains - Commonly seen on glass close to the rail way tracks. The combination of iron particles and hydraulic fluid droplets and vehicle emissions, leave a brown film on the glass surface.
Weathering - Pollutants within the atmosphere, can over time cause glass to become pitted. These cavities are then filled with particles of dust.
Stonework Cleaning - Using hydrofluoric acid to undertake the cleaning of stonework near glass, can create a reaction that attacks the glass it contacts leaving run marks on the glass surface.
Concrete and Mortar splashes - Glass in close proximity to concrete and mortar, can be subject to concrete and mortar splashes. Splashed onto the glass, it can leave a harden residue on the glass surface.
Airbourne Cement - When airbourne cement comes into contact with surface water on the glass, an insoluble film is created. This film leads to accelerated weathering of the glass.
