What causes rust to form inside my microwave?
Rust can develop inside your microwave due to a combination of moisture and metal exposure. Microwaves heat food using electromagnetic radiation, which can create condensation inside the unit, especially when cooking foods with high water content. If any food spills occur and go uncleaned, moisture can get trapped, leading to rust formation over time.
Another contributing factor is the presence of any scratched or chipped areas in the microwave’s interior. The protective enamel coating can wear away, exposing the metal beneath to humidity and moisture. Once the metal is exposed, it becomes more susceptible to rusting, particularly in the humid kitchen environment.
