I've got a still fairly bright and shiny Caldera Cone. I've been using it with USP pure ethanol. I like that because I think it leaves my caddy "clean" to use as a cup or bowl. Being in California though, it may be my next trip to Arizona before I get everclear as a replacement fuel. I don't like methanol because any leak makes my caddy "dirty." So I was considering a Gram Cracker to bridge the gaps when I don't have the pure ethanol available. But would it leave a different/worse residue on my Caldera Cone, and make my caddy "dirty?"
