Corning Thermos with pouring spout -- spots inside

walker | Aug 31, 2009 12:29 AM

I would like to know if I should throw this away.

It looks fine still, in every way but one: there are spots on the inside, sort of greyish-black that don't come out with soaking and washing. I used to use it to keep coffee hot.

Is it ruined or dangerous to use?
