Our kitchen's GE microwave oven is still working fine, but the white
paint on the oven floor is cracked and peeling off where the rollers on
the round three wheeled carriage under the rotating glass dish have been
rolling over it for a few years now.
The bare steel is exposed and getting slightly rusted and the peeling
paint trail is widening. Its appearance mildly annoys me every time I
see it.
Anone know what paint(s) are suitable for brushing over the worn area to
improve appearances? Perhaps one of those little brush top bottles of
white appliance touch up paint would do the trick.
I'm thinking that because the paint is right up against a metal surface
it probably can't absorb much of the microwave energy and get heated
anyway.
Thanks guys,

I think you're right to be concerned about exposed metal on the inside of
your microwave, primarily because of possible electrical arcing and

I had a microwave with nothing but metal walls, ceiling, and floor.
No paint at all. I don't think arcing is a problem here. He can
check further by removing the dish and the trivet and warming a cup of
water. I'll bet there will still be no arcing. Uncovering more of
the metal won't make it worse.

The walls are not hot, even when cooking, which is why one can clean a
microwave just by boiling water in it. Food dries on but does not get
"cooked on". Just cook something and then touch the wall or the the
place on the floor with no paint, and you'll see it's not hot.

Only polar molecules are heated, and I gather it's only the polar
molecules with a resonant frequency the same as the oven's. That is,
water.

secondarily because of aesthetics There are several glossy, enamel paint
products available that are designed to cover exposed metal and make
things look better, too. Some of the paints come in a small tube with an
applicator, like car touch-up paint. Check around online or call a local
appliance parts/repair place since markups vary widely. Oil will work its
way underneath the margins of your current wearline and cook, which may
likely exacerbate your current problem. Powdered teflon might be okay for
ongoing friction, but I would never use it unless people with chemistry
and medical expertise could assure me that it's not carcinogenic,
especially in a microwave where we prepare food at high heat to be
ingested. Sheesh, we're not even supposed to cook in plastic, so there's
no way I'm using teflon in there. Be sure to follow directions with the
paint, including thorough shaking of the paint and cleaning the surface
thoroughly of anything greasy or wet so that the paint will adhere.
