Pellet oxidation

I’ve read where people used Coca-Cola, vinegar and other concoctions. The first thing I tried was CLR and put them in a small jar and twirled the jar around a little bit and let them sit overnight and then the next morning rinsed them off with warm water and then drain the water off and put them on a paper towel and roll them around then used a heat gun set on low and kept it moving and dried them off.They looked like new again.Then you can lightly lube them with whatever you want.
