From my experience PLA on glass should be a quite reliable, even more if the bed is heated mildly like 50-60C - if glass on heated bed reaches like full abs temperatures the glass may crack and break.
Perhaps there is something else wrong, with the acetone or temperatures. Imo, try hijacking your girlfriend/wife supplies for some nail polish remover which at content says only acetone and water, and try with that one instead, just to be sure. Or perhaps your extruder pla temperature is too low and plastic gets cooler before reaches the bed, hence wont stick, so try measure heater temperature with a tmermocouple multimeter to check if thats the case.
