"the water that dripped off it into the sink was speckled with black coloring"

If I'm understanding it correctly, I'd guess the record was made from PVC and possibly the carbon black additive has leached from it, but I think that would require a chemical reaction. In this case the problem seems to be some sort of physical degradation on that side of the record. You may be able to tell by looking at the grooves under a strong magnifying glass. Possibly that one side of the record has been exposed to strong sunlight, sufficient that UV light has changed the surface of that one side, made it much more brittle, and the specks are flecks suspended in the rinse water.

I don't know whether exposure to sunlight (and the concomitant UV) would leave that side misty as a result of the carbon black leaching. The misty might now be the permanent state of the record. I hope someone comes along with the answer.
