Also -- I still dont' see how CLR would help. It's the cold faucet turner to the bathroom sink. I cannot get the damned thing off -- how would I put it into a bucket or bowl of CLR. If I could do that then the problem would be solved.

Instead, I would have to figure out how to spray it on the sink and risk damaging the porceline, and counter top. It cannot be immersed unless people have figured out how to do that upside down.
