We have done some preliminary testing of Soto's Appliance + Porcelain Touch Up inside a microwave, and the paint was not damaged and it retained its durable properties. That said, there may be other issues relating to microwaves, and we make no claim that it is going to safely repair your microwave. We recommend that you check with the microwave's manufacturer to see if the interior can be painted, since many manufacturers say that once the interior paint starts flaking or peeling, the microwave needs to be replaced.
