I have just been cleaning my microwave and noticed that its getting quite rusty. The rust is both in the corners ( been there a while) and now on the door but its not in holes anywhere.
Is there a point at which a microwave becomes unsafe because of this? Or can I use it until it blows up?
The microwave is about 20/21 years old. It still functions (as in heats, defrosts etc) and doesn't appear have any problems.
Anyone know if I should have a new one on my Christmas wish list whilst my Fairy Godmother is with me at the moment?
