What causes rust in a microwave?
Rust can develop in microwaves due to a variety of factors, primarily related to moisture and the materials used in their construction. When the paint or enamel coating on the interior surfaces becomes chipped or worn, the underlying metal can be exposed to moisture, leading to oxidation and rust formation. Additionally, if food spills are not cleaned promptly, the moisture from these spills can contribute to the rusting process as well.
Another contributing factor is the microwave’s environment. If a microwave is located in a humid area, such as a kitchen where steam frequently accumulates, the increased moisture can accelerate rusting. Over time, rust can not only affect the aesthetic appeal of the microwave but also compromise its functionality and safety.
How can I safely remove rust from my microwave?
To safely remove rust from your microwave, begin by unplugging the appliance to ensure safety during the cleaning process.
