Step 1: Unplug the Toaster. Make sure the toaster is unplugged from the outlet and cool to the touch.
Step 2: Gather the Necessary Supplies. You'll need a rag, warm water, distilled white vinegar and an old toothbrush. Also, make sure you have a trash bag handy.
Step 3: Clean the Crumb Tray. The crumb tray can normally be found at the bottom of the toaster, and you should be able to open it up or remove it completely. Dump all the crumbs into the trash, and remove drips or stains using a rag with a little warm water and mild dish soap. Use a toothbrush on hard-to-clean areas. Dry the tray completely and take care not to get any water inside the heating mechanism. If the toaster has extra racks or shelves, clean them using this same method.
Tip: Some older toaster models don't have a removable crumb tray; if that's the case, skip this step.
Step 4: Shake out the Extras. Hold the toaster over your trash bag and gently shake out any lingering crumbs. Don't shake too hard to avoid any electrical components falling out.
Step 5: Wipe the Outside. You can use the same vinegar-soaked rag that you used to wipe the crumb tray. For stubborn stains, use the toothbrush to gently buff them away.
Tip: Keep in mind that if your toaster is stainless steel, you'll want to use vinegar instead of water to prevent streaking.
