STOK CI grate not so great...

So I have had this thing about 8 months now.   I really like the fact the charcoal chimney fits inside the insert hole.   But when I cleaned out my grill yesterday after the ash catcher locked up on me, I found rust. This thing is porcelain coated but apparently that does not protect against rust.



From what I have been told it that moisture must have gotten on it.  Must have been dew in the month or two the grill was sitting.  On the positive side a good scrubbing with a metal scrubber then a good oiling followed by a low heat on the grill seemed to have worked.  Will now have to watch this grate and keep it oiled.
