I would clean the rust off of them, as it will help with longevity even if you don't end up using them. any of the normal rust removers like naval jelly (I've been told molasses works well) should do the trick, then you can just oil them for storage.
before you start to hone, check if the rust has taken the bevel off. if it has, you may end up loosing quite a lot of the razor to get to good steel. but get the rust off first either way. BTW, your auto-correct is pretty hilarious!
