So what?
If you notice corrosion you can just bring the oven back to the junk place
and take another with you.
(Keep the transformer if you don't have a battery spot welder yet).
Microwave ovens are usually free, because they are dumped when still quite
easy to repair. The fan blows air into the electrical compartment (usually
right) and through the cooking chamber, and out the other side. The dirty
air does not touch the electrics (it is designed that way to keep food
dirt off it). So worst case it'll start to rust somewhere...
FeCl doesn't gas much, i would not heat cucl, ever, microwave or not.
