A toaster collects crumbs that can burn, smell, and, if heavily accumulated, contribute to smoke. Clean it unplugged and completely cool: empty the crumb tray, shake out loose crumbs, and wipe the exterior. Do not insert knives, forks, or liquids into the slots.
Unplug and let it cool before cleaning
Remove the plug from the wall and wait until heating elements and housing are cool. Do not clean a connected toaster just because the lever is up; slots provide access toward electrical components.
Empty the crumb tray over a trash bin
Remove the tray as designed, discard crumbs, and wash it only if the manufacturer allows, drying it completely. Vacuum or shake loose debris from accessible areas without pressing a nozzle against heating elements.
Gently dislodge trapped crumbs
With the toaster unplugged, tilt it over a protected surface and tap gently. Do not use a metal utensil to scrape stuck bread; you can damage elements or create an electrical hazard for the next use.
Wipe the exterior without letting liquid enter
Use a lightly damp cloth and a cleaner compatible with the finish, applying it to the cloth rather than the slots. If the cord is damaged, the unit crackles, smells electrical, or has a deformed element, remove the toaster from service.
