How to Repaint the Inside of a Microwave

What You'll Need
Soapy water
Clean dry rag
Sand paper (medium and fine-grit)
Steel wool
Rust prevention spray
Appliance paint (spray or brush-on)
Small paint brush

If the paint inside a microwave is deteriorating or peeling, repainting is a possible solution instead of just buying a whole new appliance. However, not just any kind of paint is suited for this project, and there are certain preparations that need to be done in order to make the repainting a success. Here are some steps to follow for a functional and polished result.

Step 1 - Preparation

It is important that the microwave be unplugged and that the interior surfaces be prepped for repainting before doing anything else. To clean debris and grease, simply wet a sponge in soapy water, squeeze out the excess, and use it to wipe off the interior surfaces. Clean the external surfaces as well in order to simply sanitize the entire microwave while you are at it. Finish with a dry rag for faster drying time.

If the existing paint is peeling off, remove as much of it as possible, sanding it by hand gently with a medium-grit paper. Afterwards, sand it with a finer grit to smooth it out. If there are rusty spots, this procedure will also be sufficient, but you can use steel wool as well if you need. Wipe the sanded rusty parts clean, and follow it up with a rust prevention spray to stop any more from accumulating.

Step 2 - Choosing the Best Paint

There are two types of appliance paint that can be used to coat the interior of the oven: brush-on and spray-on. The best type to use is spray paint because it saves a lot of time and effort; however, brush-on paint may come in handy for small spot repairs. When going shopping, make sure not to buy just any paint on the market. Because some paints contain toxic chemicals that may enter the food in the oven, always ask for the right type. Ask the store to provide an appliance paint that is designed for microwave use.

Step 3 - Painting the Oven

Never spray paint if the oven interior is still wet or if it still has grease on it. Wear rubber gloves, safety glasses, and a mask for protection while using an aerosol paint to avoid any health risks.

As soon as all preparations are complete, start spraying the microwave until the paint covers the surface completely. Avoid spraying too much in one area; try to keep your coat of paint as even as possible all around.

For the brush-on type, simply apply the paint consistently on all surfaces. Wait for the paint to dry completely before using the oven. It is recommended to allow it to dry overnight while the door is still open. Do not close the door because obviously this will prevent air flow from getting into the microwave, which will slow down your dry time. The next day, touch the paint to check that it is ready for use.
