Cooking spray can be convenient for preventing food from sticking to pans and dishes when using conventional ovens or stovetops. However, using cooking spray in a microwave oven can pose several dangers and should be avoided. Here are the main reasons why cooking spray is not recommended for use in a microwave:
Fire hazard: Cooking sprays are flammable, and when sprayed directly onto the interior walls or components of a microwave, they can ignite and cause a fire. The intense heat generated by microwaves can quickly lead to combustion if the cooking spray is exposed to it.
Damage to microwave interior: Cooking sprays may leave a residue on the microwave's interior, which can be challenging to clean and may damage the microwave over time. The residue can also interfere with the microwave's proper functioning.
Harmful fumes: When cooking spray is heated, it can release harmful fumes and particles, posing health risks to those using the microwave or consuming the food.
To avoid these dangers, it's best not to use cooking spray in the microwave. Instead, use microwave-safe cookware or cover your food with microwave-safe lids or wraps to prevent sticking. If you need to add oil or butter to your food before microwaving, it's safer to do so directly on the food rather than spraying it onto the microwave's interior or cooking surface. Always follow the manufacturer's instructions and guidelines for safe microwave use to prevent accidents and ensure the longevity of your appliance.
