@johnelle This is a fairly common issue with glass beds. They are great but you must keep them very clean. And Alcohol should not be considered a cleaner. First of all set you bed temp back to 60 C for PLA anything higher and you create new problems for yourself.
I have several printers with glass beds and this is how I maintain them.
About once every couple weeks to a month I take the glass bed off and use some dish soap at the kitchen sink to get it nice and clean. Then as long as I don't do anything silly, I can get away with just using a damp paper towel. This glass has tiny facets that your filament sticks to. If those facets are filled with any debris, then your print will never stick. I never use Alcohol, Magigoo, glue stick or anything else on my print surface. Please note that if you print PET-G, you may want to put down some glue stick or Magigoo (which works better) because PET-G sticks too well and can damage the glass. The other alternative is to wait until your print pops off the bed on it's own before trying to move it.
That is the only real downside to glass beds, you really should let the bed cool down before you try to retrieve you print or there could be trouble.
Hope you find this helpful.
