Why a burnt smell coming from your toaster is not a good sign. Toasters should be regularly cleaned on the outside and old crumbs removed from the inside.
Unplug the toaster before cleaning. If there is fat residue on the heating elements, use the device's grease cleaning function. Never use sharp objects such as knives or forks to clean the device. Other household appliances such as dishwashers can also be damaged if you make mistakes while using them. If you have pungent food smells in your home, home remedies can help neutralize them.
