just out of curiosity - have you tried reheating the bed at least partially before attempting to pry off the part? perhaps that would help?

personally, I have not had any success with the hairspray, but the glue stick works pretty well for me.

edit: I follow you put the parts with the broken glass stuck to them in the microwave.

I just put it in the freezer after the print and it slides off in about 3 minutes

There are a multitude of folks out there that wish they had some of your problem! 

I have never separated glass like that....... wouldn't know how to do it if I had to.

The reason I clean so often is I am trying for consistency - trying to turn the art of adherence into a science.  I find I can modulate the stickiness very well by changing the extrusion width for first layer parameter in slicer.  For small parts, I go with 100% but for a large part prone to warping, I will dial this all the way up to 200% and it works quite well (as you can see :-)).  The bigger thread holds more heat and has more time to adhere.

I think the problem is the hairspray actually adheres more as it cools so if I set the extrusion low enough to not permanently adhere when cool, it doesn't adhere enough when hot for large prints.  Maybe I should try different hairspray.  I am not using the recommended Aquanet ultrahold  since the generic hairspray at Walmart has been working really well (except for this issue).  I'll find some Aquanet and see if it behaves any differently.

OK I am no expert on the subject of glass and hairspray but WOW!  You have definitely nailed the adhesion process.
To answer your question, one of two things works for me.  Let it cool and it will simply come loose or use a razor blade scraper to get under one edge then work all the way around the part.  Don't pry up just keep working around the edge until you can get no more blade under (about 1/4").  Then pry slightly and it should peel up or pop off.  If not then let is cool some more and repeat.

Seriously though you are simply cleaning your glass too much and using way too much hairspray.  I like that you have taken the process to the extreme limits as it shows just how powerful the bond can be.  But if a simple single light mist on the glass (maybe every 10-15 prints) doesn't adhere your prints to the bed, there is a good chance something else isn't correct.
I am a huge proponent of sticking with something that works but not if it is simply masking some other issue.

The only time I have trouble is if I'm in a hurry and want to get it off the glass before it is cooled.
