How to clean a microwave oven

Microwave is one of the kitchen appliances used by many families today. It is often used to reheat food, defrost or prepare some simple foods. During use, there are many types of food spilled and scattered in the oven, making the microwave become a “bacterial nest” that causes illness for the whole family. Therefore, you need to clean the microwave regularly to ensure food safety and hygiene during cooking. In this article, mycookingtown will show you 7 simple ways to clean a microwave oven, which can remove all stains and odors from the microwave.


Notes when cleaning the microwave:

  • Before you start cleaning the microwave, unplug it and prepare a soft cloth to clean it, to avoid scratching the oven.

  • When you want to clean the microwave, you should pay attention to cleaning the tray or rotating surface of the oven because this is the part where the food is placed, so it should be quite dirty. You can disassemble the tray or the movable surface and clean it by soaking in warm water with dishwashing liquid, then rinse and dry it.
  • When cleaning your microwave at home, you absolutely avoid spraying water directly into the oven to clean because this will greatly affect the life of the microwave.

When cleaning the microwave oven, you should be careful of using strong detergents because if they are not totally washed, these detergents will be toxic for food.

Avoid leaving the rags in the oven when cleaning as they may cause a fire when the oven operates.
