Our porcelain-enamel kitchen sink has developed stains, especially
where the plastic "feet" of a "sink protector" have rested. I think
that stuff that has been dropped into the sink and not rinsed away
immediately has caught on those "feet" and remained there long enough
to stain the surface. I have cleaned the sink from time to time with
Soft-Scrub, but hat no longer seems effective, and now I find that
the stained areas actually feel rougher than the unstained areas.

Any suggestions how to fix this problem?

Depends on what the stais are. Scrubbing...bleaching...etc


First thing I'd try is to plug up the sink, put some bleach
in it and let it sit awhile.

I've done that, and it works, but only till next time: the rough surface
stains much more easily. I'm looking for a longer-term solution.

What I man is: the rough surface stains so easily that I don't think
things even have to be left on the surface: the rough surface gets
stained simply from colored liquid or other material coming into contact
with it only briefly.
