That sounds frustrating. If the toaster has a heavy buildup of burnt crumbs, grease, melted food, or other residue, you can usually clean it safely—but the most important rule is never clean it while it’s plugged in or immerse it in water.
Here are some safe steps:
- Unplug the toaster and let it cool completely.
- Empty the crumb tray.
- Remove the tray (if your model has one) and wash it with warm, soapy water.
- Dry it completely before putting it back.
- Shake out loose crumbs.
- Hold the toaster upside down over a trash can and gently tap the sides.
- Clean the inside carefully.
- Use a soft pastry brush, clean paintbrush, or toothbrush to loosen crumbs.
- Avoid poking the heating elements or using metal utensils.
- Wipe the exterior.
- Use a soft cloth dampened with warm water and a little dish soap.
- For stainless steel, wipe with the grain and dry with a clean cloth.
- For sticky or greasy residue.
- A paste of baking soda and a little water can help on the outside only.
- Wipe it off with a damp cloth and dry thoroughly.
Avoid:
- Putting the toaster in the sink or dishwasher.
- Spraying cleaner directly into the toaster.
- Using steel wool or abrasive scrubbers near the heating elements.
- Running the toaster while it’s still damp.
If the residue is melted plastic, there’s a burning smell that won’t go away, or the heating elements appear damaged, it may be safer to replace the toaster rather than continue using it.
