I would recomend Hardware store acetone, it does a wonderful job and i believe that some beauty supply acetone comes with addatives, i think bitrate might be one of them but am not sure. I seen it on the label a long time ago and someone told me why it was in there but i cant remember. The hardware store has it by the gallons pretty cheap also, jfr. When you spray butane on a dish it leaves an oil residue and when you dump acetone on a dish and let it evap it leaves nothing.
