YES! completely submerge the spur in apple cider vinegar (I use a plastic foot tub). Just let it soak for at least TWO-DAYS! The rust will fall away. Just use a toothbrush to gently clean it off in the vinegar after two-days, then rinse it off under warm water and dry it with your wife or girlfriend's blow dryer. wipe it down gently with the olive oil (Cheap olive oil!).
