Gonna clean up a couple beat up greenies, and was wondering if anyone has ever tried a white vinegar bath? I could get them blasted but vinegar is much cheaper.. thanks.. I recently cleaned up a hay hauler pully that was really encased in rust. It took a couple months but the vinegar got it down to bare metal. I think the vinegar might be harsh on the aluminum alloy the old Penns are made of or it might not work at all.
