Unplug the toaster and let it cool completely
Turn the toaster upside down over a trash can and shake out crumbs
Remove the crumb tray (if your model has one) and empty it into the trash
Wash the crumb tray with warm soapy water, rinse, and dry fully
Wipe the exterior with a damp cloth and mild dish soap if needed
Use a dry brush or soft, dry cloth to remove crumbs from the slots
For stuck crumbs, use a wooden or plastic tool to gently dislodge them
Wipe inside the slots with a dry cloth or soft brush
For stubborn residue, use a slightly damp cloth on the exterior only
Avoid getting water or cleaner into the heating elements or controls
Dry all parts completely before reassembling
Plug the toaster back in and run it empty on a couple of cycles to clear any remaining residue
