Are there any issues with using plumbing grade silver solder on (and inside) a fermenter? I just finished my new snazzy fermenter and just noticed what looks like oxidation on the solder. It's light gray, powdery, and comes off with the slightest touch. Would this be a simple case of Bar Keeper's Friend?
p.s. i'll post pics and info once i test out the design of the fermenter.
thanks!
