Got 2 old stovetops it might be fun to brew with, full of green shit that won't scrub off. Would soaking in the espresso back flush powder help nuke it off?
No need to re season, it's actually adding tannins and oils which lead to nasty flavour. A clean machine/stove top/tea pot etc will allow you to taste what your brewing, not dirt.
