I don't think you have to worry about the brazing material but you do need to be concerned about the raw steel of the bike frame once the bath is done. The brazing was probably done with a silver alloy or brass. Neither one will be weakened by any normal rust treatement.

Oxalic acid does a great job of removing rust and prepping the steel for paint. I haven't tried molasses but it's supposed to work well too. Whatever you use, you need to apply something to the frame immediately since it will start to rust again once it's exposed to air.
