If thats from trainer sweat lemme know how getting the stem outta the bike goes, I just attempted to remove the stem and bars from my miele that I spent 3-4 month trainer sessions on and the stem is seized from all the sweat that found its way between the stem and steerer tube. I guess I forgot to grease it, but even if I did remember I dont think it woulda helped too much, there was nothing but super hard stinky white salt dried up around under my locknut, under the handlebar tape wasnt pretty (not pleasent smelling) as well, its gonna be a battle royal trying to get that out.
