Sometimes use 91% isopropyl, too. Not for a full bath type cleaning, more for spot cleaning. Evaporates in no time. A quick rinse or wipe takes care of any possibility of residue. The state I live in prohibits the sale of Everclear type spirits, so that option is off the table for me, if I were inclined to pursue it. I do rather covet an ultrasonic cleaner, though. Can a decent vape-gear-cleaning sized one be had for under $50?
