Replaced battery in an iPad Air. How do you remove old gasket material on digitizer? Alcohol just makes the glue gummy. Can’t scrape with a razor or it scratches the plastic. Goo be gone doesn’t work. (I successfully used razor to remove glue from iPad case.) Buy a new digitizer? Don’t think so. At this point I’m ready to chuck Air into garbage and order an iPad Pro.
Acetone does a very good job and removing glue but just make sure you don’t get it on any plastic components in the iPad like the speaker, a plastic spudger is quite useful as well. if you have a black screen you can use a black marker to cover up the scratches.
