I have put off posting this until I was sure what was going on.This first started on the water closet door with the hinges and the TP holder turning black,
I have now replaced the TP holder with a nice oak one. Now it is the door handle and after checking the other door hinges on the cabinets they are starting to turn also. So I can for see new ones in the future. The handles on the cabinets that are opened the most are starting to lose the gold color and underneath it is sliver colored.It will be do the worst ones first because there are so many of them.
