I found that I had to use gluestick for PETG on my bedslinger - without it the print wouldn’t even stay in place for more than maybe a 60 minute print. I have heard about PETG fusing to glass beds also, though I have had the opposite problem, and I would just clean it off with some alcohol, but there didn’t seem to be much of any kind of residue.
Now, the gluestick, on the other hand, that is a nightmare, until I found the method: spray it with windex or water, let it soak in for thirty seconds or so, then scrape with any spatula-like object. I often take two passes, but wetting the glue turns it into a looser sorta paste that comes right off. Once all the glue is off, go over it with alcohol to dry it all up, clean as a whistle.
