I have a full sized microwave, had it for close to 20 years, and inside I can see several places where the metal is showng, the interior lining has, mostly on the bottom portion, and lower back wall. Is this safe to cook with? I have been using it, and it does a good job, just concerned about possible radiation leaks, etc. How safe the food is to continue eating I heat up or cook in it. Or should I get a new one? Thanks for your answers.
