Fabricating Debris on Glass

The sound (Gary Mauer) of fabricating debris on glass (video courtesy of window cleaning resources).

I've been putting off the subject of fabricating debris for quite a while now, as its such a body of work that needs addressing and is coming to the forefront in the window cleaners world, although the problem has been around for much longer. If it hadn't been for the work of Gary Mauer & Dan Fields, more window cleaners would probably have gone out of business by now.

Gary Mauer runs a widely respected network & has educated window cleaners worldwide on the problem of fabricating debris & Dan Fields educates via his website, tapes & DVD's.

If you are not familiar with the problem, I urge you to sign up now to the discussion group or get the information from the websites concerned, click on Gary & Dan to take you straight to their respective sites.

The issue here is why some uncoated tempered glass (but not all) may be so laden with abrasive fabricating debris that it will scratch when you clean it with a standard window cleaning scraper. Fabricating debris is an inherent problem with tempered glass, but clearly some temperers do a good job of minimizing it, while others do not.

Lately a war of words has broken out between GANA & window cleaners in the USA. With GANA contradicting themselves by saying scrapers shouldn't be used, but.......a small scraper could be used???

More links from the AUWC with their defective glass bulletin & an open letter to GANA from the IWCA. The MWCoA also put out a great pdf file with some excellent pictures. Make sure you have a waiver in place before attempting any builders cleans, some window cleaners reserve the right for a signature before any window cleaning is attempted on any glass.
