The Best Kept Secret In Construction Window Cleaning
In recent years scratched glass in the construction industry has become a major issue for Builders and Construction Window Cleaners alike, with no solution in sight.
I'm a third generation window cleaner with over 40 years construction window cleaning experience, with a work force that has cleaned over 4500 houses for local and national builders per year.
In an attempt to educate builders and window cleaners on the causes for the majority of scratched glass in the construction industry, I've build a website: www.StopScratchedGlass.com. This web site describes various causes of scratched glass and solutions to eliminate them. The majority of the site clearly illustrates where the majority of glass scratching is coming from and what I feel is the best kept secret in window cleaning, Razor blades & Scrapers Do Not Scratch Glass - Fabricating Debris Does!
Over the past several years window cleaners have been experiencing and getting blamed for excess scratching on tempered glass. In resent years it's been discovered poor quality tempered glass has caused the majority of this glass scratching and as a result the glass industry has taken a new position that scrapers should not be used to clean glass. They have also attempted to contend tempered glass surfaces are different. With this position by the glass industry, more facts on this subject must become more available to both Builders and Window Cleaners and that's why I've gotten more involved with my web site.
The problem and the solution is very simple. It's very important when tempering glass to temper only clean glass, which is why all glass should be sent through a glass washer before being tempered. Glass washing prior to tempering is essential to remove all fabricating debris generated during the fabricating process and glass washer maintenance is critical if clean glass is to result from this process.
Any contaminated glass entering the tempering furnace will result in a glass surface defect. This glass defect becomes the problem when cleaning glass. With normal construction window cleaning techniques, glass defects are dislodged and dragged across the glass surface, resulting in excess scratching over the entire surface of the tempered glass. These defects can been seen through a 10X magnifier, with the scratch beginning at the defect.
