About 5 yrs ago, I replaced my bathroom sink fixtures with a Moen brand.
Currently there is an unsightly rusty buildup around the sink drain/plug
hole. What would cause this?
Also, how do I get rid of it?

Most tap water contains dissolved minerals
(e.g. calcium and iron) that precipitate on
water fixtures e.g. faucets. CLR and other
chemicals can redissolve them
