Is this amply demonstrated or is this hearsay? I ask because I have used unscented isopropyl 91% for sterilizing and destinking bowls/stem interchageably with Everclear 190-proof and never had problem 1. Only problem I ever heard of (for sure) with iso was from folks who fouled pipes with alcohol that had scent- or bittering agents.

I think a clear, definitive evalution of iso is important as many among us are unable or unwilling to purchase grain alcohol. I'm not sure I know about one.
