- Unplug the appliance: Safety first.
- Use a vinegar and water solution: Mix equal parts and place in a bowl. Heat this mixture in the microwave for 5-10 minutes to loosen grime.
Inspecting for Damage
Always check the microwave for any visible signs of wear and tear, such as a broken door latch or frayed power cord. This is essential for ensuring that the microwave operates safely.
What to Do If Your Microwave Blows Up
While the goal is to prevent an explosion, it’s good to know the appropriate response should an incident occur.
Evacuate the Area
If you notice smoke or confront an explosion, your first course of action should be to leave the area immediately.
Call Emergency Services
In the event of flames or a significant explosion, it’s imperative to call your local fire department.
Safe Practices to Follow
By adhering to these practices, you can minimize the chance of accidents in your kitchen:
