That way, you can enjoy your perfectly toasted bread without a side of fire extinguisher residue.

How Can a Full Toaster Crumb Tray Really Cause a Fire?
Toast is notorious for creating crumbs. The evidence of said crumbs is often highly visible on your butter if you're not careful. It also falls off of the bread and into the bottom of the toaster. The bottom of the appliance can also accumulate other particles, like sesame seeds from your bagels.
Excessive crumb buildup could get close to the heating elements, which glow with heat when your toaster is running. The crumbs will also heat up, potentially burning and charring. It's possible for that to lead to flames inside of the toaster.
Overheating due to crumb buildup is also a potential toaster fire hazard. If the crumbs block the vents, it could force the kitchen appliance to work harder and overheat.
Even if the fire starts small, the flames could grow and shoot out of the toaster. Nearby cabinets, food packages or other flammable items could then ignite, allowing the fire to spread.
How to Clean a Toaster Crumb Tray
One easy way to minimize this toaster fire hazard is by cleaning the toaster crumb tray regularly. This prevents potentially dangerous crumb buildup.
Supplies to Clean a Toaster Crumb Tray
You don't need much to clean a toaster crumb tray. Grab a soft-bristled brush or clean toothbrush to help remove stuck-on crumbs gently. A damp cloth is also helpful for wiping interior and exterior surfaces. Vinegar is another cleaning option for the exterior of your toaster.
Steps for Cleaning Crumbs Out of a Toaster
The following steps make cleaning the crumb tray easy:
Unplug the toaster to prevent accidental shocks. The toaster should also be cool.
Pull out the crumb tray from the toaster. Look for a little pull-out section at the bottom, either at the front or back of the appliance. Holding the appliance over the trash can may reduce the mess.
Dump the crumbs from the tray into the trash.
Shake the toaster gently over the trash can to dislodge additional crumbs that are still inside the appliance.
Wash the tray in warm, soapy water. Rinse it and dry it well.
Use the soft-bristled brush to wipe away any crumbs from inside the toaster.
Wipe the outside of the toaster with a damp cloth. Add a little vinegar to the cloth for extra cleaning power.
How Often to Clean the Crumb Tray
The frequency of cleaning your toaster crumb tray depends on how often you use the kitchen appliance. If you make toast daily, clean the tray at least once per week or more often if your bread has seeds and other additives that fall off. Families who only use the toaster occasionally might only need to clean the tray every few weeks or even once a month. Keep an eye on the buildup to get the timing right.

Toaster Fire Hazards
While crumb buildup is one of the biggest toaster fire hazards, it's not the only issue. These additional hazards (and ways to prevent them) are also worth knowing:
Older or damaged components. As your toaster gets older, the parts can wear out and cause the appliance to malfunction. For example, the heating elements might continue running when you're done toasting, causing it to overheat. Consider replacing your toaster if it's older or doesn't seem to work well anymore.
Electrical cord issues. Frayed or damaged wiring or electrical cords can cause toasters to start an electrical fire. Inspect the visible wiring regularly, and replace the toaster if you notice issues with the cord.
Flammable items inside. If an unexpected item falls into the toaster, it could catch fire from the heat or from contact with the heating elements. Check the inside of the toaster each time before you use it to spot unwanted items that could have fallen inside. Avoid storing the toaster where objects can fall inside.
Nearby flammable items. Even if a flammable item doesn't fall inside the toaster, it could still catch on fire if the material gets too close to the heating elements. Position the toaster away from drapes, towels or other items that could get close to the heating elements.
Overcooking toast. Leaving a piece of bread in the toaster for too long could also start a fire. This could happen if you have your toaster on the highest setting and leave it unattended. Sometimes, you might push the toast back down if it doesn't get dark enough the first time. Not watching it closely could set the toast on fire.
Being aware that your toaster is a fire hazard and knowing how to minimize those issues makes the appliance less scary. Regular cleaning and careful, supervised use can help you enjoy your toast safely.
