Can I repaint the inside of my microwave? What type of paint is best after removing the rust?

 

Don't go by just my recommendation, but I think a good start would be an exterior enamel meant for metal. This would be after removing every last speck of rust and applying a quality primer, also meant for metal. Your local Sherwin Williams would be a good place to ask this question, as they are a "coatings" conglomerate, as opposed to just sellers of paint. Of course, the expertise of the folks at the store may not extend to some of their more esoteric products, but they may be able to ask somebody who does know.

Whatever you do, don't expect the job to last long. I expect the factory finish is baked on, which is not something you could do at home, and the heat and steam inside a microwave are a tough challenge for any coating.

Microwave interior spray paint is available.

 

If paint specific for microwaves is available I'd use it! Most any rust inhibitive primer followed by an oil base enamel will stop the rust but since this is a cooking appliance I'd be concerned about paint fumes interacting with what you are cooking might not be a problem after it is used several times

 

If the inside of your microwave is rusty you should dispose of it
It's a safety issue

 

I would agree with Slick. With the cost of microwaves below $100 bucks for a decent unit I would chuck it and buy a new one.

 

I think that if there is specific microwave paint, it should do just fine. I don't see how rust is a safety issue. Sure, rust holes would be a problem, but I don't see how surface rust is going to make it unsafe.
