Thanks, Gammer0. I've done the cleaning, and poked around. It's not food related, it's very much a machine/oil smell. However, I think I've gotten use to it. I noticed it upon returning after being away for a while. Not sure if it's a *good* think not to notice it, but...well, you know, trying to deal with foremost things on the to-do list. Appreciate it, though.
