Because glass fines are generally invisible to the naked eye, touching the glass - prior to using a scraper - is the best way to detect fabricating debris before potentially damaging glass surface. You should (but not always) be able to feel the tiny pimples of the fabrication debris even when you can't see them. This raises the question: "Who's responsible for damages when glass fines get caught under a scraper blade and scratch glass"? Is it the window cleaner or the glass manufacturer? (See the RED BOX below for more info).

When using a scraper, to remove over-spray, always test blades reaction to window glass in a small inconspicuous place, such as a corner of the glass. Glass fines will have a "gritty or course sound" when scraper moves across glass. If you hear this, STOP scraping!!! You'll want to choose a different method to remove paint over-spray and other construction materials such as, via a "0000" grade steel wool pad or with the use of the appropiate chemicals.

Can you get a refund for glass you've purchased containing glass fines?

Probably not. Since glass fines do not effect the structural integrity of the glass and are not a hindrance to glass clarity, the glass will usually meet Industry standards for heat treated flat glass. This again questions the idea of "Who is responsible"? If you are a home owner and you follow your window scraper's manufacturers guideline to scrap glass and as a result you damage the glass surface because, the manufacturer of the glass has provided you glass with fabricating debris baked into it's surface. Shouldn't this be cause for due negligence on the window glass manufacturer? Shouldn't they be liable for replacing your glass? (See the RED BOX below for more info).

Professional Window Cleaner's - "Damage Waiver":

If you are a professional window cleaner providing a "construction cleanup window cleaning service", you should strongly consider using a damage waiver to legally excuse your company for damages that may or have already occurred before your service commences. Afterall, glass fines are very difficult to detect, making it easy for you or one of your employees to accidentally damage a clients window glass surface.

Also, scratches and other damage may already be present on glass surface but, not noticed until "After" you've cleaned the glass. This is obviously damage incurred by a previous contractor, or during shipping/ storage or manufacturing of the glass product. Unfortunately, you may be stuck with the bill so, get a waiver signed before performing construction cleanups and other related work that could expose your company to liability issues. Check out "Window Washing - Post Construction Clean-up" for more info.
