Heavens to murgatroid! Double whammy on that one! That's why most tire shops won't deal with split rims. When I was a military mechanic if we didn't have a tire cage handy we would put the ring on the underside and sit on top of the tire in case this happened. I knew of a guy that didn't do that and the ring popped off of the rim and crushed his larynx. Ugh.Good thing you weren't standing next to it with one foot propped on it.
Denture cleaning tablets work pretty well too.I bought a pair of pedals. The blocks are in decent shape, but there is rust pitting in the metal.

So I’m going to try something I have never done before, and I’m going to break them apart.

Now I’m going to grind, sand and smooth all of it that I can then get it plated. I’m sure there will still be some pitting, but they will look a whole lot better. I’m going to bleach the blocks in hydrogen peroxide to knock the yellow out as well.
