We bought a relatively new home (2001), and for some reason, the built-in microwave has rust in the back corners.
Besides from sounding gross, I'm wondering if there is any possible health risks with heating food up in this microwave?
The food does not directly touch the rust, but I'm not sure exactly how microwaves work and if the rust can become airborne. Does anyone know? Also, I'm not sure what the cause of the rust is; I've never had a microwave do this before (so, possibly the cause of the rust may be more significant than the rust itself?)
thanks!
