You got it wet and dried it back out? I've gotten holsters and belts pretty wet. I just dry them and go on.
If you want to clean them, saddle soap.
If you want to wax them, atom balm, neutral shoe polish, or renaissance wax.
If you feel like it's dried too much and needs some oil a light coat of neatsfoot oil or saddlers oil. Be warned, oil softens leather. Too much can make a holster useless. Light coat.
