hydraulic coffee mug

[sossol]

It was Taiwanese oil (this was made prior to the Chinese MFG exodus), and how could that not improve the flavor?

I washed the reservoir with solvent, foaming degreaser, and finally, Dawn dish soap, so I'm sure that there's no oil left in or on it. My sense of smell was ruined years ago, so even if it did smell of oil, I wouldn't know. My brother-in-law said that it just smells like raw steel, though. Plus, I make coffee strong enough to eat with a fork, so that smell would overpower all others anyhow.
