I'm with y'all on the vodka, the though of a mishap with isopropyl alcohol gave me the "Howard Hughes'" as my kiddos tease me ...what's the old saying "you can date Ethyl but best stay away from her sister Methyl, she'll kill yah" so when presented with my first cleaning, I took a look to the liquor cabinet, Absolut and then you can drink it when you're done!!vaping and a cocktail...ahhhhh *kidding* just a lil bit in the bottom of a glass and a swirl did the trick.
