Is It OK to Use High-Temperature Grill Paint in a Microwave Interior?

Peeling paint inside a microwave oven can be more than just a nuisance.

Common Gloss Enamel Will Work

If the high-temperature grill paint is a gloss enamel, it will be suitable for painting the interior of a microwave.

Look for Peeling or Flaking

If the paint on the oven's interior is peeling or flaking, it can be a sign of more serious problems, and the microwave should be replaced.

Bottom Line

Any gloss-based enamel will work to paint the interior of a microwave oven, assuming the current paint is not flaking or peeling. Sand down the current paint and any rust, then cover with gloss-based enamel paint.
