Microwave ovens, including the interior of the cooking chamber, do not typically have Teflon-coated surfaces. Teflon is a brand name for a type of non-stick coating known as polytetrafluoroethylene (PTFE). While Teflon is widely used in cookware like frying pans and baking sheets, it is not used as a coating inside microwave ovens.
The interior of most microwave ovens is made of stainless steel, which is a durable and easy-to-clean material. The use of stainless steel ensures that the microwaves are effectively reflected within the cooking chamber, promoting even cooking and preventing hotspots.
While Teflon itself is considered safe to use in cookware when used correctly and not overheated, it is not suitable for use inside microwave ovens. When exposed to high temperatures, Teflon coatings can release harmful fumes, which can be a health concern.
To ensure safe and effective microwave use, it is essential to follow the manufacturer's instructions, use microwave-safe containers, and avoid using cookware with Teflon or any other non-microwave-safe materials inside the microwave oven.
