If you want to remove smells from inside a microwave oven without disassembling it or using soap and water, here are a few methods you can try:
Lemon or Vinegar Steam: Fill a microwave-safe bowl with water and add either a few slices of lemon or a tablespoon of vinegar. Place the bowl in the microwave and heat it on high for a couple of minutes until the water starts to steam. The steam will help loosen and eliminate the odors. Afterward, let the microwave cool down, then wipe the interior with a damp cloth.
Baking Soda: Sprinkle baking soda on a damp sponge or cloth and use it to wipe down the interior surfaces of the microwave. Baking soda is known for its odor-absorbing properties and can help neutralize unpleasant smells. Once you've wiped the surfaces, rinse the sponge or cloth and wipe again with clean water to remove any residue.
Coffee Grounds: Place a small bowl or cup filled with dry coffee grounds in the microwave and leave it inside overnight. Coffee grounds are effective at absorbing odors, including stubborn smells. The next day, remove the coffee grounds and discard them. You can also heat the coffee grounds for a short period to release their aroma and further mask any lingering smells.
Citrus Peel: Take the peels of citrus fruits like oranges, lemons, or grapefruits and place them in a microwave-safe bowl with a bit of water. Heat the bowl in the microwave for a minute or two until you start to smell the citrus aroma. The natural oils from the peels will help freshen up the microwave and counteract any unpleasant odors.
Remember, it's always a good idea to clean up any spills or food debris inside the microwave promptly to prevent odors from lingering. Regular maintenance and cleaning can go a long way in keeping your microwave smelling fresh.
