Carb King's term "deathanol" is a good one. The stuff is hygroscopic (absorbs water) so if it sits for any length of time in a gas tank anywhere except maybe the Mojave desert, it's going to get corrosive. That white powdery residue that clogs up carburetor passages in one that sits idle for a while is caused by moisture. I wonder how it got there? I've had pretty good luck with using Sea Foam in the gas tank of my Harley when it doesn't get ridden for a few months in the winter, but I also run non-ethanol gas whenever possible.
