Total Glass Care

By "Total Glass Care" I mean going way beyond just window cleaning. Glass surface restoration involves removing scratches, and mineral deposits. It also involves the rejuvination of etched surfaces. In particular static etching which appears as a milky white film. This happens when an HF solution makes contact with the tin side of float glass. It also happens when etchant vapors make contact. Such as in a crystall glass shop. Sulfuric and hydrofluoric acid are used at very high concentrations at around 175 degrees fahrenheit. The vapors from the vats travel through the room and condense on the inside of the windows. Here they mix with water vapor forming acids that react with the glass. It is the reaction byproducts (white salts) that are left behind. Total Glass Care also involves minor repairs. Holes and cracks. It includes repairing IG units that have lost their seal. Removing polyester solar film. Applying clear films for scratch protection. Also the application of different sealants to help in removing mineral deposits, or resisting scratches, or improving vision by beading rain. Total Glass Care also involves inspections for damage done during construction, transport, or from the factory. Tempered glass can be excessively wavy. Or the surface can be defective having millions of microfines embedded from the tempering process. Windows might not have a low e coating on the inner surface of the unit. There are simple tests that will show it up. Actually there are a host of problems that the untrained eye can't quickly pickup. All windows should be inspected when they arive on the construction site, when they are installed, and when the job is finished. Total Glass Care involves so much more than just cleaning windows. It goes way beyond what a typical window cleaning company can offer. Not to mention janitorial companys that focus on vacuuming carpets, wiping desktops, mopping floors, and removing trash. And oh yes, once in a while they might use a bottle of Windex on the door windows to knock off the fingerprints. If your building has fifty thousand plus in glass, it is in your best interest to hire a Total Glass Care company to routinely inspect, protect, repair, and maintain your windows. This is an ongoing technology. But it is my determination to keep on working at improving for the benefit of my customers.
