My bathroom faucet fixture was installed in 2008. The round drain plate that sits right on the sink (where the stopper rests to prevent water from going down the drain) is corroding faster than the rest of the faucet fixture. Overall, the fixture looks practically brand new while the round drain plate is starting to look very old. It's peeling, turning green and getting crusty around the edges. The corrosion was caused by water pooling around the plate.
Is it possible to replace just the round drain plate or do I have to replace the entire faucet fixture? Not that I would replace the entire thing at this point. I was wondering what my options would be in the future. The faucet model is Moen Kingsley, widespread, double lever handle if that helps.
Here is a picture of what I'm talking about. Sorry for the big size of the picture. Thanks for any replies.
