Can you paint the inside of a microwave?
Yeah! Absolutely you can, provided you take safety majors!
Oftentimes, we make a mistake by using ordinary paint. It cannot withstand high heat. This in turn results in the microwave exploding, minor sparking, or fire inside the microwave in rare cases.
So, repainting with microwave-safe paint is the first-step to safety!
Another mistake we make is that we do not inspect the rust or peeled off area. Diagnose the rust always before you repaint. Whenever sparks occur inside the microwave, the microwaves have gotten exposed to bare metal walls. Otherwise, the rust damage is so widespread that there are holes inside the microwave oven cavity. At those times, the repair by repainting is next to impossible! If oven damage is more, consider purchasing a brand-new microwave.
In such cases, repainting the inside of a microwave won’t make things turn better!
Is it safe to paint microwave cavity?
Yes, it is safe to paint microwave cavity. Until you’re using a microwave-safe microwave cavity paint and painting properly, you’re playing a safe bet! Know the right painting technique before repainting the microwave.
If you’re painting appliance exteriors, then no space for worrying! The exteriors are built tough enough. So, generally, they do not cause any damage to the microwave. Removing rust on exteriors and repainting exteriors is a safe-game!
While repainting the inside microwave cavity, only use microwave-friendly paint. The microwave oven paint must not get hotter by high heat as you run the microwave for cooking. The rest is taken care of!
Is it safe to use a microwave with peeling paint inside?
Absolutely not at all! No! Never use a microwave with peeling paint inside. It is a risky bet you take on!
The paint is a protective-layer for metal interiors of a microwave. Metal is not microwave-safe. There are free electrons moving inside the metal. When they get in contact with microwaves, they reflect waves rather than absorbing.
As you paint a metal wall cavity, you make it microwave-protective! When this paint peels off or flakes, the metal walls become vulnerable to microwaves. So, there are chances of a mini lightning bolt or arcing inside the microwave. At times, it can also result in fire hazards. Or else, it can leach contents into food causing food contamination. Such a thing is riskier for health.
Can you use high heat paint inside microwave?
Yes, only high heat paint can resist microwaves! Other paints might leach its contents causing food contamination.
A microwave paint must withstand temperatures up to 1200° Fahrenheit. Enamel paints generally withstand high heat. So, they are perfect for microwave repainting purposes.
We suggest you use Rust-Oleum high heat paint. It smoothly paints the inside of a microwave. Also, even after it dries up, it can withstand hot temperatures of microwave ovens.
Can you paint the inside of a microwave with appliance paint?

Also, repainting a rusty microwave works only when rust is under control. In other words, repainting works when rust is minimal. Make sure that rust hasn’t covered bigger microwave areas. Also, rust is not penetrating holes inside a microwave. As well as, the rust on microwave exteriors mustn’t make its way to eat up the internal cavity.
As all these three cases are extremes, you’ll be asked to replace the microwave. Also, it’s a better option now as rust is now out-of-control! Rather, purchasing a brand-new microwave is the best decision.
What kind of paint can you use on the inside of a microwave?
There are two kinds of paint available in the paint market. One is spray on paint and another is brush on paint.
Just check if it’s labeled as microwave-safe! Also, perform a microwave-safety test to double check. Repaint a smaller area inside the microwave. Run the microwave by placing a cup of water inside. Once the microwave stops, check if the painted part is no warmer than other non-painted parts. If it doesn’t feel hot, you’re in for that enamel paint and vice-a-versa.
Moreover, check the ingredients listed on the back of the paint package. There must not be any materials that are microwave-sensitive. For example, metallic items. It reacts slowly with the microwaves resulting in the sparking.
A spray-on paint is suitable for coating larger microwave cavity areas. Simply spray the areas that you wish to repaint. The spray does the task! It saves a great deal of effort and time. On the other hand, brush on paint is suitable for coating smaller repairs. If the rust is small, you can simply brush over the coats on the affected area. This is how other non-rusted areas stay intact as well.
Moreover, you can use a combination of two as well. After you spray the area, there will be places that aren’t coated well. Use a brush to repaint those spaces in the cavity. It covers the finishing spots and does excellent polishing.

Touch-up kit or sheets
Inside every microwave, you’ll find a shiny waveguide cover. Sheets are generally suitable to replace this waveguide cover. These sheets are made up of silicone resin mica paper. It’s highly heat-resistant.
Inside a touch-up kit, you get everything like brushes, sandpapers, stirrers, etc. As all tools & equipment are existing in one box, you can finish the repainting tasks in one-go. Your microwave will look new-like after repainting!
Any paint you select must be heat-resistant. So, it applies to all & any paint. Only buy a paint that can withstand high heat temperatures. It must not be designed for microwave exterior parts. Rather, it must be specifically designed for the inner microwave cavity.
You don’t want high chemical paint that is hazardous to health! So, check beforehand the ingredients of the paint. You can check out the product back-side to do so. Your paint must be non-toxic.
If you use a toxic chemical paint, it can contaminate food & drinks. While your microwave is running, the paint can leach its substances into food. Do not purchase low-quality paint options. Rather, go for high-quality best paint options.
