Yesterday I tried Crunchy Betty’s “Alvin Corn” glass cleaner (ALcohol+VINegar+CORNstarch). I used vodka in place of the rubbing alcohol because, strangely, I have vodka, poitín, Everclear, and moonshine on hand, but not Isopropyl alcohol. I’m pretty sure our little-used liquor cabinet violates some sort of hazardous materials storage guideline.
Ramblings aside, I highly recommend the glass cleaner. Works like a charm, doesn’t stink like the blue stuff, costs pennies, and you can put it in a sprayer you already have instead of buying another one.
