I thought it wasn't possible. I have a 5 qt french oven bought back in 2001 and that I absolutely love using. The last thing I did was boil penne pasta in it last night, and a few pieces of pasta bits stuck to the bottom and dried a bit. We got lazy and left the dishes for this morning. Hubby let the pot soak a bit in water then scrubbed as usual with dish sponge (scotch brite kitchen sponge). Next thing I knew, there are white spots along the interior bottom which upon closer look was where enamel had been chipped away! I know we've had food stuck on it before that came off with a little light pressure and was cleaned and ready to go. What did we do wrong this time? Is there any remedy or do I have to invest more money in a new one?
