Rust inside of microwave

Just curious - are you saying the ingredients in the appliance paint are not flammable once they have tried and we are using the microwave?

The liquid propellant is the most flammable part of paint.

Once that evaporates (the paint dries) what's left is not as flammable.

But high temperature appliance paint can withstand the temperatures in the microwave.

High-temperature appliance paint is available from places like Wal-Mart, Lowe's or Builder's Square.

Can you use appliance spray paint inside of a microwave oven


Well, sort of, yes.
However. If I had this job, and I have done this several times already, I would :
1)Scrub the inside squeaky clean, and sit it out in the sun for a couple days to dry out.
2) Take masking tape and newspaper and cover the punched hoses grid and any light bulbs so paint will not get inside the machine works or on the bulb.
3) Spray just enough paint to do the job,
4) Again sit it out in the sun for several days to make sure it is dry and free of "fumes" as the paint is highly flammable, and the machine could even blow up if you do not air it out.
God bless your efforts.

Inside of microwave top peeling and blistering


If it's paint peeling, then once that paint is gone, rust will set in, which can cause arcing and disintegration of the chassis, when ruins the oven.

This peeling is usually the result of excess moisture accumulating in the oven due to blocked air vents or poor fan circulation.

Once those two issues have been ruled out or dealt with, then always be sure to dry out or leave the microwave open after use.

The peeling paint will need to be removed, then the area should be sanded.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

I have a Danby Designer Microwave, model DMW1153W, 1100 W, and there's a dime sized rust spot on the inside of the microwave, it's along the crease where the back of the microwave is joined to the...


Rust can form from the steam and condensation as you say, and it's a good idea to always cover food and wipe the oven out after using it. You can sand off the bad paint and rust the same way you can on a car, and then touch up the paint if it's a minor amount. Spray paint specifically made for microwave cooking cavities is available. (You don't want to use paint that may have metallic components.) It may be available locally if you have appliance parts stores in your area, and you can find the paint online as well. There's no need to replace the oven just yet, unless you find a good deal on a new one and you're looking for an excuse.

My microwave inside bottom paint is peeling off. I would like to know if there is special paint that cam be use safely to fix it. PD. It is not a matter of buying a new one. Is the challenge of fixing...


You can only use appliance paint which can be bought from the local home improvement store.

The exact instructions will vary from brand to brand and type of paint application used but you can follow these general steps:

  1. Clean the appliance thoroughly with soap and water and leave to dry.
  2. Apply a treatment on rust spots to prevent the rust from spreading or showing up through the new paint.
  3. Unplug and move the appliance to a well-ventilated area or create good air circulation in the painting area.
  4. Remove or protect areas (such as handles and other decorative details) on the appliance that should not be painted.
  5. Paint the appliance according to the product instructions.
  6. Let dry thoroughly before moving.
  7. Apply a second coat if necessary.

Whirlpool gold GT4175SPS-2 inside door paint is flaking and revealing metal. Is it safe to use?


Hi,

Scratches, flaking and bare spots are fairly common, but should be addressed as soon as they arise so the corrosion will not spread and arcing does not occur.

Unplug the power cord first.

Take some mild sanding cloth or scotchbright and clean the bare and rusted areas in the microwave. Use appliance touch up paint to re-coat the surface. You can find the touch up at most anywhere that sells appliances, it comes in a plastic bottle similar in appearance to fingernail polish, yes it does have a brush inside.

Let it dry per the instructions on the bottle or 24 hours if not specified.

Microwave safety after repainting


Too generic...Did you use the high-temp appliance enamel recommended, or a spray...or worse?

Was the rust inside where it can contact food through the circulating air, or on the outer body?

First thought based on how I read the question: Never use that machine again...but that's based on the word "in" instead of "on my microwave".

If the rust was around the door frame, outside the seals, and you used an enamel (of course) then you may be OK...but...
Considering the fact that a cheap microwave is a drop in the bucket when compared to your family's health...Why risk it?

Bottom of door inside badly rusted - oven works fine


Yes you can paint it.. Begin by removing the rust with either a wire brush or a thick paste product called naval jelly. Then prime the area and finally paint it with appliance paint, abailable in a spray can at most hardware stores in the color of your appliance.

My microwave oven has are rust spots;can I paint over them?


Yes, you can paint over the spots and no, it's not dangerous. I'd let the paint thoroughly dry before using the oven -- it could otherwise cause paint to buckle/ripple/etc.

Paint has chipped off bottom of MW


Moisture accumulation can sometimes be caused if the cooling fan is not running properly or if the vents in the back are blocked or there is not enough free space around the sides and back of the microwave.

One thing that helps is to keep the door open a few minutes after using it and to wipe down the inside after use.

If the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean and dried thoroughly.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

Popcorn stain in Microwave


Uhhhmmm, paint? Inside a microwave? YUCK.... that would make food taste like paint.

The yellow stain from microwave able popcorn is most likely a permanant issue. I have heard of the vinegar water, bleach etc working, but never had it work for me.

I don't recommend you painting the inside of a microwave. Some paint is flammable. Almost all paints are toxic.
