Are these damaged?
The two sinks in our rental property have developed these marks. They are completely smooth to the touch with no scratches being felt when running my fingertips over it.
Our rental agency is trying to claim $320 from our bond claiming that the sink is damaged and needs to be repaired/replaced but I feel like that is a bit too much.
They are pretty stubborn and did not seem to go away no matter what we tried.
