Inox is a lubricant, you should never clean electronics with something like that, pure denatured alcohol, or spray contact cleaner that evaporates completely are good choices, you should re-clean it, and don't use medicine cabinet alcohol it contains mostly water. You shouldn't try to recharge those types of Lithium cells they don't tolerate it, but if it was just to test that's fine, definitely replace the battery though. I wouldn't recommend super glue either it doesn't tolerate vibration well so in a rough and tousle key tossing world you should probably use something like a high temp melt glue gun, or an epoxy designed to remain flexible, loctite might work but it's not recommended for plastics. If you do use super glue anyways use the slow stuff, the fast cure time is what makes superglue so brittle, something to do with the way the accelerant works.
