I'm so happy I don't need to buy a new pot
My coffee pot had a black residue on the inside.  I was told it was called tannin.  I tried several different products and I couldn't get it off.  I used Squeak'n Clean with hot water and let it soak for a few hours.  My coffee pot came out sparkling clean. I'm so happy I don't need to buy a new pot!
