Paint inside microwave oven, Can it be repainted ?

Hello -

Yes the rusted areas inside a microwave oven can be repainted.

First, you will need appliance paint which is designated for microwave interior use. Check with your local hardware store or local home improvements store to find out what paints they sell which fit the criteria for "microwave cavity paint."

You can read directions for how to go about the project:

Read the instructions through, completely, before starting on your project so you know what supplies you need to have available and what steps need to be followed before starting.

Best wishes.

inside your micro... walls are made of metal but protected with paint, if this paint is gone and the metal shows thats what happend you have to repaint the unprotected areas again, and the reason your micro... is not working so good anymore is due to the magnetron

see the troubleshooting section and follow the steps and fix it.
God bless you

Waveguide Cover

If the microwave is sparking or arcing the waveguide cover might be damaged and shorting out. Try removing the waveguide cover and see if the problem goes away. If there are any damaged spots in the microwave ceiling or sidewalls, repair them and paint them with microwave oven paint. Replace the waveguide cover if it is burnt or if it will not stay in place.

Microwave Oven Paint

If the microwave is sparking or arcing on the side walls the paint might have chipped causing pitting in the metal oven wall. Use microwave safe paint to touch up any bare metal spots.

Rack Support

If the microwave is sparking or arcing near one of the rack supports, remove the support, repaint any bare metal, install a new support.

Yes you can repaint it. Use an epoxy based paint and clean the metalwork with sand paper first.
The only health question is if you get the flaking paint in your food - yuk!

Small areas inside the cavity can be repaired. The bare spot must be very smooth. You can sand it down if needed and then repaint. There is a m/w cavity paint sold in a spray can, but I've had really good luck using regular appliance touchup paint. Just be sure the spot is very smooth when you finish. Use several thin layers of paint instead of one thick layer and you should be ok.

it is not safe to use this, DO NOT USE, repalace immediately, no need to repaint

Is it plastic or paint? I would be surprised if it were plastic, as that would probably not withstand the microwave energy.

If it needs to be repainted, that can be done if it is cleaned and dried.

High temperature appliance paint is available from stores like Wal-Mart or Lowe's.

Either one should be fine, but usually appliance paint is high-temperature paint.

The main thing is to be sure the surface is squeaky clean & dry before painting. If the surface is rough, I'd sand it smooth first.

This may have already been dealt with, but others can benefit from an accurate, thoughtful reply to this problem.

You can sand the peeled area, even the rusted area in most cases, clean them squeaky dry, and repaint with high-temperature appliance paint available from places liek Wal-Mart, home improvement centers, and appliance parts stores.

No need to replace the microwave if you can clean and paint it properly.
