The short answer
Why Fire Residue Is a Problem
After any fire, even a small one, smoke and soot can find their way into the microwave's vents, seams, and internal wiring. This residue is corrosive and can damage electrical connections over time. It can also cause the microwave to overheat or short-circuit when you turn it on.
The metal surfaces inside the microwave can retain soot, which may affect how the appliance heats food. In some cases, the residue can give off a lingering odor or even transfer to your food. For these reasons, a simple wipe-down is not enough to make the microwave safe.
What to Do Before Using It
Unplug the microwave and leave it unplugged until you are sure it is safe. Do not try to clean the inside of the microwave yourself if you see heavy soot buildup. The internal parts are delicate, and improper cleaning can make the situation worse.
Contact a qualified appliance repair professional to inspect the microwave. They can check the wiring, the magnetron, and the control panel for damage. If the microwave has been exposed to high heat or water from firefighting efforts, it may need to be replaced entirely.
- Unplug the microwave and do not use it
- Do not open the microwave if it smells like burning plastic
- Avoid using water or cleaners inside the microwave
- Check the power cord for melting or scorch marks
- Look for any visible warping or discoloration on the exterior
- Ask a professional whether repair or replacement is the better choice
Fire and Water Damage Together
If firefighters used water to put out the fire, the microwave may have gotten wet. Water and electrical appliances do not mix. Even if the microwave looks dry on the outside, moisture can be trapped inside the casing, creating a serious shock or fire hazard.
In a humid climate like Daytona Beach, moisture can linger longer and cause corrosion to set in quickly. If your microwave was near any water spray, treat it as unsafe. Have a professional check it before you even consider plugging it back in.
When to Replace Instead of Repair
Microwaves are not expensive to replace compared to the risk of a fire or electric shock. If the microwave is old, or if the fire was intense, replacement is often the safer and more practical option. A professional can tell you if the unit is worth fixing.
Look for signs like a warped door seal, a cracked glass plate, or a damaged interior. These issues can affect how the microwave contains radiation. If you notice any of these, do not use the microwave, and plan to replace it.
Cleaning After a Professional Check
If a professional says the microwave is safe to keep, they will likely recommend a thorough cleaning. Use a mild cleaner and a soft cloth to wipe down the interior and exterior. Do not use abrasive pads that can scratch the surface.
After cleaning, run the microwave with a bowl of water inside for a few minutes to help remove any remaining odor. If the smell persists, the residue may be too deep to clean. In that case, replacement is the safer choice.

Can I just wipe the microwave and use it?
No, a simple wipe-down is not enough. Soot and smoke can get into internal parts where you cannot see them. Only a professional can determine if the microwave is safe to use again.
What if the microwave looks fine on the outside?
Damage from fire and smoke is not always visible. Internal wiring and components can be affected even if the outside looks clean. Always have a professional inspect the microwave before using it.
Is it safe to use a microwave that got wet from firefighting?
No, water and electricity are a dangerous combination. Even if the microwave is dry on the outside, moisture can remain inside. Unplug it and have a professional check it before you use it again.
