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
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. That was the first thing I'd thought of, but the "track" is
depressed into the oven bottom and has sloping sides, which are also
missing some paint now, but maybe a ring of poly sheet as you siggest
will take care of the flat surface the wheels roll on and some white
paint will replace what's flaked off the sloping sides.
I think I'll try that..
I'd wipe the rusted area with a little cooking oil or shortening and
forget about repair work. Most of my appliances working over 15
years look a little worn too (cooktops, dishwasher racks, dented sink,
etc), but glad they still work fine. Glad Martha S. doesn't live
Don't know how the oil film would hold up. Only a rust through would let
microwaves out. Cheap for a basic unit, not so cheap if used as an
excuse to upgrade to an Advantium or similar. Of course the old unit
could migrate to the workshop for reheating coffee while working on a
I started a fire in my microwave once, thawing a loaf of bread and had
forgotten to take off the
metal twist tie. My son asked, "What's burning?" I said, "What do you
mean?" He pointed at
the microwave and the flaming bread wrapper. Very small amount of
flame, and no damage done.
So, that leads me to ask about exposed metal inside the mw.....dangerous?
Not if used properly. In the early days of microwave ovens they simply
said not to use metal in the microwave, assuming (possibly correctly for
the time) that consumers were not sophisticated enough to understand the
actual restrictions on using metal in a microwave. More recent microwave
oven user manuals and microwave cookbooks give the real instructions,
which mostly amount to: No sharp points and not too close to the oven
walls. I readily use stainless bowls in the microwave and leave spoons
in containers in the microwave without issues. Microwave instructions
and cookbooks also tell you to use aluminum foil to shield thin areas on
foods from overcooking. Your metal twist tie violated the "no sharp
points" rule, concentrated the energy and caused arcing which started
Phisherman's suggestion of wiping with cooking oil is a good one.
Been using that technique to keep my 1984 Panasonic countertop
microwave from rusting at the rotary tray wheel path.
I clean under the rotating tray every so often. The paint is only
gone on the wheel path so I can only see it when the tray is out.
I was thinking about painting but figured the paint wouldn't hold up,
plus the light oil rub has prevented any rust damage.
I think you're right to be concerned about exposed metal on the inside of your
microwave, primarily because of possible electrical arcing and 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.
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,

I would just go with a good epoxy paint, or maybe even just a good Rustoleu
m spray paint. HEAT is not an issue, only wearability.
