How to Repair Microwave Interior Paint

If your microwave contains rust, you probably want to know how to repair microwave interior paint. Whether your damage results from misuse or regular wear and tear, you could touch up the paint using a microwave-safe enamel or a designated interior microwave paint.

However, some of the best microwave brands recommend simply replacing your microwave if serious damage occurs. For example, you should not try to repair large spots of peeling paint or arc marks. If you have issues with your turntable, you may want to learn how to fix the turntable in a microwave.

Repairing the Interior Paint of Microwave Ovens

Although the process of repairs to paint can be time-consuming, you may want to improve the appearance and function of your microwave. You will need sandpaper, microwave-safe paint, a paintbrush if you use liquid paint, and soapy water. If you have a lot of food build-up, you may need a scrub brush or paper. Before you begin, you should decide if you can safely complete the repairs, according to Sears. GE states that there is no safety guaranteed process.

Steps for Painting the Microwave Oven’s Interior

1. Remove the glass plate and spinner. You don’t want to get paint on these appliance parts. Additionally, you reduce the chance of the glass plate breaking.
2. Clean with soapy water and a dishrag or paper towel, and then scrub off any dirt. If you haven’t washed it in a while, you could need more time to clean under the glass turntable and the roller guide. To loosen any food remnants that are particularly hard, heat a cup of water for a minute or two before wiping with a washcloth. Follow up with a dry cloth.
3. Sand off any rust or remaining peeling paint until you see metal. You may want to use paint thinner to get rid of the paint. However, the rust should come off with the sandpaper only. Remove any rust before attempting to fix the interior paint, or it could break off. If there’s a large hole in your microwave oven, GE recommends replacing it to avoid arcing during use.
4. Smooth the surface with sandpaper. Make sure to sand the surface where you want to paint because the paint will stick better.
5. Unplug the microwave, eliminating the light from the microwave itself and reducing the heat inside.
6. Cover the light, vent, and edges of the microwave. In doing so, you ensure your paint only covers your desired surfaces.
7. Vacuum out the remainder of the dust on your surface, preventing dust from getting trapped under your paint. At this point, you may want to pull gloves on to protect your hands from the chemicals and paint.
8. Block the hole in the middle of your microwave with a stopper of some kind. This hole leads to the turntable motor. Getting paint on here could hurt your motor.
9. Apply your paint. Make sure to shake any type of paint before use, with at least 2 minutes of shaking for spray paint. The paint can be microwave-safe enamel or microwave cavity specific. You must apply the paint evenly, so you may want to test it first. You may need a second coat of paint. Then, leave your microwave door open as it dries to help air it out and rid your appliance of the smell.
10. Let the paint dry for a day or two.
