My gasket is bright and shiny except for these few freckle like places where the black is being stubborn. Most of them are in the crease that squishes, but some are on the flat sealing surface. I started with Charlies soap, then used a Mr. Clean magic eraser and now have had it soaking in bleach. I'm going to look for the Mold Control product you mentioned GoodDogShelby. Thanks.
ShellyBelly, I've been thinking of using a toothbrush, but was trying to avoid it. I got my freezer on CL, and after a thourough cleaning these few places are the only thing remaining. Other than a dent and few scratches.
