Hi Shannon. I don't know from personal experience if the bubbles can be seen, though my daughter says they can. A house guest accidentally cleaned our new HD TV screen with water, causing similar bubbles. My family could tell they were there because part of the picture was blurry. They did go away after a week or so. If you're getting clear scans, your scanner should be fine. If not, leaving the lid open to let it dry out will help. I don't think there is any permanent damage to worry about. It sounds like others on this list are managing well while cleaning with water or glass cleaner. I'd say that means you're probably going to be fine. I'm kind of cautious and literal about following instructions on my computer equipment. I have never cleaned my OpticBook or Canon with anything but my soft cloth. However, back in the early days of scanners, I cleaned my HP ScanJet with glass cleaner with good results.

I mean, is there a way to tell if this has happened? And, if it has happened, is there anything that can be done about it? ----- Original Message ----- From: Monica Willyard <mailto:rhyami@xxxxxxxxx> To: bksvol-discuss@xxxxxxxxxxxxx Sent: Thursday, January 14, 2010 8:35 PM Subject: [bksvol-discuss] Re: Question about cleaning scanner glass I think it depends on the scanner. Many newer scanners, like the OpticBook and newer Epsons and Canons, aren't really glass. They're Plexiglas, and it's porous. Those scanners shouldn't be cleaned with any liquid because the moisture will get trapped inside the Plexiglas and will create little bubbles that will distort your scans. This is true of modern laptop screens, monitors, and TVs too. These scanners' instruction manuals say to clean them by wiping the scanning area with a soft, static-free, lint-free cloth. You can either buy these at a computer store, or you can make your own from an old pair of cotton underwear or an old, white cotton T-shirt.
