? on cleaning Tempered glass on french doors

With no risk to seals, frame, etc.?

How does one “softly scrape?”

How does that “lessen the risk?”

Why would a professional window cleaner scrape a CCU window dry?

Do you currently provide customer education regarding fabricating debris, and require a signed waiver for any and all (including CCU and maintenance) WC’ing?

What is corking?

The only proper way to scrape is in one direction, lift scraper, and repeat.
Oh, and waiver, waiver, waiver!:wink:

I to am concerned about scratching tempered safty glass how about the manufactures caulk per pane left that needs to be removed.
