I cured some belly using Bears step by step instructions and all turned out good but I had it resting in the fridge on a jerky rack and evidently some of the coating is missing here and there. This is the third time I have made bacon and washing the racks must of exposed metal. long story short there are some black spots where the meat touched bare metal. Looks like a chemical reaction. They are Cabelas racks so I thought they would of been better quality. My question is, is the whole piece ruined or can I cut those spots out?
