I have a late 40's era brass Schick Injector magazine that I want to load with new blades and use, but the blades in there (it looks to have the full 20 or close to it) won't eject. The first three or so came out, but now they won't budge as they appear to be stuck together. Would a soak in warm, soapy water loosen them up? Would boiling cause any harm?
