    Goo Gone is what I usually use for adhesives/sticker residue. I then follow it up with Iso Prop. to get rid of the citrus residue. Works great. However try it out first to make sure it doesnt remove the marking.

    If you don't have goo gone, you can use Mayonnaise. Yes the condiment. It gets rid of sticker residue too. Don't laugh until you try it. Just use Iso Prop after to get rid of that residue...

    I keep a small bottle of 50/50 acetone and 70% isopropyl Alcohol on my workbench, great for removing flux after soldering and makes quick work of removing labels from Ceramic Eproms.

    Not good however for anything with plastic. It also wipes the markings from all of the Remarked/Counterfeit IC's from China

    On a cerDIP UVEPROM, exactly what are you trying to avoid damaging? Short of HF, I don't know of much that will affect the encapsulation, though I'd keep acids away from the leads.

    In the old days, I'd probably use Freon TF.

    Since I've never just sprayed it on, I don't know what effect it would have on the "window". Probably none, but, I do like to be careful.

    I just use isopropyl alcohol, it works well enough.

    The window has to pass short-wave UV, so it's quartz (SiO2). Quartz is pretty tough stuff.
