What is the purpose of metal rack that comes in some microwaves and it safe to use microwave with place?

The metal rack, also called a microwave shelf or tray, serves several important purposes in microwave ovens:

Elevating Food: The primary function of the metal rack is to elevate food above the bottom of the microwave oven. This allows heat from the microwaves to circulate evenly around the food, ensuring more consistent and thorough cooking. By keeping the food slightly elevated, it helps prevent uneven heating and cold spots.

Preventing Food from Sticking: The metal rack helps to prevent food from making direct contact with the bottom of the microwave. This prevents food from sticking to the bottom and makes cleanup easier. The spaces between the metal bars allow excess liquid or fat to drip down, reducing the risk of splattering and messy cleanup.

Promoting Airflow: The metal rack allows for better airflow inside the microwave oven. By elevating food and creating a space below, it facilitates the efficient circulation of hot air and microwaves throughout the oven, leading to more uniform heating.

Safety Considerations:

Using the metal rack that came with your microwave is generally safe. These racks are designed specifically for use in microwaves and undergo rigorous testing to ensure they do not pose any safety hazards.

However, it's important to follow these guidelines for safe usage:

-Never use metal utensils or cookware inside a microwave oven. These can create electrical arcs and damage the microwave or cause serious injury.

-Check the manufacturer's instructions for your specific microwave model. Some models may have restrictions or specific guidelines for using the metal rack.

-Ensure the metal rack is clean and free of food residue or grease before using it in the microwave.

-Avoid touching the metal rack immediately after microwaving, as it may be hot. Allow it to cool down before handling.
