From my experience USA isopropyl alcohol (70 percent = 140 proof) ....seems to have an "additive."
I get a white/chalky film residue after using it.

My reason for premium Vodka is no sugar....

Perhaps, EVERCLEAR 180 proof, with DISTILLED water.

However, water is the unversal solvent in the natural world....and too much alcohol might discolve more than transitory stain.

I have cleaned hundreds of Yinyl records with Vodka...some totally encrusted with mold/mildew, as with women, be soft, be gentle, caress the groove with a compassionate pleasure.

Sincerely,
