Road salt from riding outside in the winter is much more damaging to your bike than your sweat.
did you look at the link i posted? Or just google sweat corrosion on trainers, people have damaged bars, stems, even BB areas on aluminum frames from sweat
the damage is most common under bar tape where it can't be wiped off and is allowed to sit and not evaporate as quickly
