Leaving the microwave door open when cleaning was a practice that was once recommended as a safety precaution to allow any lingering odors or fumes to dissipate. However, it is not a common recommendation anymore, and most microwave manufacturers do not suggest leaving the door open during or after cleaning.
The reason for this change in advice is primarily due to safety concerns. Modern microwave ovens are designed with safety features and ventilation systems to prevent the buildup of harmful fumes or odors during normal operation. When you heat food in a microwave, any odors or steam are typically released through the built-in ventilation system.
Leaving the microwave door open while cleaning might not significantly improve ventilation and could potentially pose safety risks. For instance, the door is an essential part of the oven's safety mechanism, and keeping it open may prevent the microwave from functioning correctly or even cause damage.
Instead, here are some safe and effective ways to clean your microwave:
Use a microwave-safe bowl: Place a microwave-safe bowl with water and a few tablespoons of vinegar or lemon juice inside the microwave. Heat the mixture on high for several minutes until it steams up the interior.
Wipe down the interior: After the steam has loosened the grime and stains, carefully remove the bowl (it will be hot), and use a sponge or cloth to wipe down the interior of the microwave.
Clean the turntable and accessories: Remove the turntable and any other removable accessories, and wash them with warm soapy water. Rinse and dry them thoroughly before placing them back in the microwave.
Regarding cookware, glass and microwave-safe plastic containers are commonly used because they do not react with microwaves and allow for safe and even heating of food. While metal containers were once discouraged due to the risk of sparking, modern microwave-safe metal cookware and containers are now available and designed specifically for use in microwaves.
To summarize, leaving the microwave door open during or after cleaning is not recommended for safety reasons. Instead, follow the cleaning guidelines provided by your microwave's manufacturer and use microwave-safe materials to ensure safe and efficient operation.
