You have several options. Ammonia works well, the general household
method is to pour ammonia on the stains, then seal the thing in a
plastic bag for several days before removing, rinsing and washing. Oven
cleaner won't hurt corningware, I use one that doesn't require heat and
let it sit for whatever ammount of time stated by the manufacturer. Mr.
Clean or Scotch Magid Eraser sorks well for this sort of thing as well.
