Can these cups be saved?

[Jhrudkaj]

I stumbled across this site when looking for cleaning tips. I picked these mugs up at a junk store for ten bucks in hopes of restoring them to their former glory. I'd love to use these for making Moscow mules. I just hope they can be resurrected. I'd love to hear your tips for cleaning these up. Keep in mind I want to drink out of them.

TIA,
Joe
