I've watched the video of the process using ethanol and acetone. The ethanol looks liked it's used to dilute the acetone to make the solution less aggressive to the Styrene acrylate copolymer used in the toner. Acetone is also miscible in isopropyl alcohol. 99% isopropyl alcohol is readily available at a pharmacy like CVS or Walgreens. I use it to clean electronics and optics. It cost me less than $3 per 16 ounce bottle. 99% isopropyl alcohol may be a good substituie for the ethanol. I'll give it a try, just won't be able to get to it for a couple of weeks.
