Durable paint for the inside of a microwave oven

We have a well functioning microwave oven with a rusty circular track on
the bottom of the oven where the plastic wheels supporting the rotating
glass dish have rolled for several years.

The track looks awful and it's spread to about 3/4" in width now, much
wider than the wheel treads and I'm thinking it may soon rust right
through the oven floor.

I tried painting it with white automotive touchup paint a while back,
but that only lasted about a week before flaking off.

Can someone name a really tough white paint, maybe an epoxy based one,
that I can use to put a heavy durable coating over that rusty "track"?

Failing that, I guess I can take the time to cut a circular band out of
aluminum or stainless sheet metal and epoxy it over the rusted area with
conductive epoxy to avoid the possibility of it arcing to the oven
floor. But that's a bit of work and prolly guarantees that the microwave
will decide to die soon. <G>

Thanks guys,

Jeff

The stain may remain, but there are ways to mitigate without painting.

I do NOT recomend painting inside a microwave. Who knows what's
thepaint going to do.

There is a product called Wink that is mild HF acid with wll remove
almost anythign related to rusting. However, use gloves!

We use a quaternary compound called Unicide 256 from Brulins in
Indiana. That compound removes, reduces rust back to the original.
Not originally intended for that, but it does do it.

We spray it on, rinse off and the rust is always all gone, plus,
cleaned.

rustoleum makes an epoxy paint in a rattle can, used for changing the
color of appliances. available at the borg. it does take a while to
harden fully if you can't warm it up some.

I don't understand flaking off, but epoxy is what I was going to say. You
can't just spray it on top rusty oily surface. I usually use a hair dryer
to speed setting up, and let sit a 2-4 days.

How did you prepare the metal surface before painting it? Because
even car touch-up paint should have lasted a lot longer than a week,
but in general you don't want to use it in a steamy environment
because it's lacquer and is much more porous than enamel. You
should have sanded down to the original primer or to bare metal
and prepared the bare metal with phosphoric acid to make the paint
stick better. Naval Jelly is phosphoric acid and removes rust.
You don't need epoxy paint, just any non-toxic enamel that doesn't
contain pure metal (almost any white enamel will do). Appliance
parts supplies and MCM Electronics sell spray-on microwave oven
cavity paint that's suitable.

Some touch up paint is lacquer. Not all. Having metal or conductance in the
paint will not matter. It's too close to the metal to have any effect at
this frequency.

I have the exact same problem with my MW. It's a GE Brand. I've wanted
to do something about it, but never have. I thought about sanding it to
remove the rust and just coating it with JB Weld. As long as I use the
slow drying stuff, it should settle and make a smooth surface.

I think it's poor design that causes this. Yet the MW itself has always
worked flawlessly.

Yes, you can paint it. Would never have happened to begin with if you would have cleaned it like this each and every time since it was new: take a wad of paper towels and wet it really wet, put it in the microwave for two minutes. Take a dry wad of paper towels and put over the hot ones to remove them. Wipe out the hot damp microwave with the dry wad. Works every time and doesn't rust your microwave either.

Unless there's a spill that I wipe out, I only clean the oven every
few months and I do it by boiling a dish full of water and then wiping
it out, and I never have any rust.

>Isn't that baked on paint originally?

The paint on my washing machine was baked on but the e-pox-ee spray
paint I used was as hard as new and never chipped. It's amazing but
it's so.

100 dollars is a lot of money for some people. You never seem to
notice that. A half-can of epoxy paint costs 5$, and you'll find out
how much it smells when you're done. I'd venture that after a day's
drying or two and 20 minutes boiling water, even to make coffee, there
won't be any smell. This group is home repair, not home buy new.

I agree about the buying new bit.

I'd suggest the epoxy paint. But let it sit for at least 24 hours, or
48...

I had a MW that rusted around the rollers under the rotating tray. It
was getting real bad, and I was going to paint it too. The MW died
before I got to painting it. So I had no choice but to buy a new one,
because the main board died and was not cost effective to repair.
Actually the part was more than twice the price of a new MW.

Apparently they only sell parts to suckers and idiots....

Don't use any metal rings anywhere inside the Uwave. Even on the floor of the oven, if it is not in complete bare metal to bare metal contact with the bare metal floor,there will be circulating currents in the metal ring that will make it get hot, and you might get arcing/sparking also. A ring made of non-metal material should be ok as long as it remains electrically non-conducting. That means no spills, etc., which are hard to completely eliminate in a real-life kitchen.

And you added what to a post from 2012?

It has a baked on finish and no paint will work well and be durable.
You could have it done professionally for about twice the cost of a new

In alt.home.repair, on Thu, 26 Dec 2019 16:23:08 -0500, Ed Pawlowski
About 35 years ago I got a washing machine off the street. It had a
couple small problems (intake filter clogged, lid switch broken) and
some damage to the cabinet.

I painted it with iirc E-POX-EE spray paint, White Appliance color.

Afterward, of course I didn't try to damage it but it sure looked and
felt just like the rest of the machine where the paint was good, and it
lasted without damage for 5 years until the main basket bearing rusted
shut and I couldn't get it apart to fix. (If I'd used the machine more
often, the main bearing might not have rusted into one piece.)

Despite the name, there was only one can and no mixing.

I now Jeff has moved on, but, after sanding of course, I would spray
some paint into a disposeable cup and paint it on the track. If only
to see how long it lasted.

Removing rust or treating it first with converter. I would still use self

stainless, no paint except outside door and cabinet.
