I took the plunge and bought a resin printer. I was wondering if I could use full strength home-brew vodka at 90 % instead of using isopropyl alcohol before anything is added to clean prints with?

I cannot seem to find anywhere or anyone that has tried this.

    $\begingroup$ Isopropyl Alcohol is the more common choice for cleaning surfaces because it evaporates more rapidly than ethanol and also because it does not leave any traces of oils upon evaporation. $\endgroup$ – apesa Sep 17 '20 at 5:38

    $\begingroup$ To add one more caveat. Homemade alcohol no matter the proof / % will have many fusile alcohols that will deposit themselves on your semi cured resin. 90% alcohol dosen't equate to clean solvent. $\endgroup$ – apesa Sep 17 '20 at 6:06

    $\begingroup$ You can cheaply and easily turn 70% IPA into 99.99% IPA by adding table salt to the bottle and shaking it up, then inverting the bottle, unscrewing the cap slightly, and squeezing out the brine layer on the bottom until pure IPA comes out. Or baste/siphon the top layer. Only works with IPA. Science FTW. $\endgroup$ – dandavis Sep 18 '20 at 8:10
  • $\begingroup$ @dandavis nice thing! You happen to have a resin printer and can do an experiment? Use that on contaminated IPA and see if it cleans up the IPA! $\endgroup$ – Trish Sep 18 '20 at 10:48

Isopropyl-Alcohol - Propan-2-ol - and Ethyl alcohol - Ethan-1-ol - are different chemically. As a secondary alcohol, Propan-2-ol has quite different solubility of different materials than ethyl-alcohol.

Now, let's look at home made alcoholic destillate. That stuff is, if done in one refraction and without tossing the first low temperature part, some percentages Metanol, Ethyl alcohol and maybe some water. That has not the same solvent properties as Propan-2-ol.

While it might work, nobody will sign a guarantee that it doesn't negatively impact your print.
