What is the best way to clean microwave that has brown popcorn stains on inside walls?

To clean brown popcorn stains from the inside walls of a microwave, you can follow these steps:

1. Prepare a Baking Soda Paste:

- In a small bowl, mix baking soda and water to create a paste.

The ratio should be approximately 2 parts baking soda to 1 part water.

2. Apply the Paste to the Stains:

- Use a soft cloth or sponge to apply the baking soda paste to the popcorn

stains on the inside walls of the microwave.

- Ensure that you cover the stains thoroughly.

3. Microwave the Paste:

- Place a cup of water in the microwave and heat it for 3-5 minutes

on high power.

- The steam generated from the water will help to loosen and soften

the brown popcorn stains.

4. Allow the Paste to Sit:

- After microwaving, let the paste sit for an additional 5-10 minutes.

This will give it time to work its magic on the stains.

5. Wipe Clean:

- Open the microwave door and use a clean, damp cloth to wipe away the softened popcorn stains and the baking soda paste.

6. Rinse and Dry:

- Finally, rinse the inside of the microwave with a clean, damp cloth to

remove any remaining traces of the paste.

- Wipe dry with a paper towel.

7. Deodorize (Optional):

- To remove any lingering odors, you can place a bowl of white vinegar

in the microwave and heat it for a few minutes on high power.

8. Repeat If Necessary:

- If some stains persist, repeat the process until the microwave

walls are completely clean.

Tips:

- Use a soft cloth or sponge to avoid scratching the microwave's interior.

- Do not use harsh abrasives or scouring pads as they can damage

the surface of the microwave.
