My glass plate is clipped onto the aluminium plate under which is the heater PCB. Under that I inserted a black insulating blanket used to shield the joists while soldering copper pipes. I found that by insulating the bottom of the moving bed that more of the heat is retained and what i reported by the temperature sensor matched the heat measured on the glass plate.
I use Bon Ami cleanser to clean the plate of the microscopic thick plastic residue and oily finger grease and that is often enough. And if not I add a thin film of hair spray. You also have to look at the engineering of the part and how it will shrink upwards and lift off the plate. Sometimes just adding extra pads that you cut off later helps hold things down.
