Cleaning a toaster oven with harsh chemicals can potentially be dangerous if not done correctly. The use of harsh chemicals may leave residue or fumes that could be harmful if they come into contact with food or are inhaled.
Using a tray filled with water and letting it evaporate over an hour on high heat is not a recommended method for cleaning a toaster oven. It's important to follow the manufacturer's instructions for cleaning your specific Hamilton Beach toaster oven. Typically, toaster ovens should be cleaned using mild, non-toxic cleaning agents, and you should avoid using harsh chemicals inside the cooking area.
If you've already used harsh chemicals and are concerned about residues, it's best to thoroughly rinse the interior of the toaster oven with water to remove any remaining chemicals. You can also wipe down the surfaces with a mild detergent or baking soda solution to help neutralize any potential residues.
Remember, the toaster oven is a kitchen appliance, and any cleaning method you use should prioritize food safety. If you have concerns or questions about how to clean your toaster oven safely, it's best to contact Hamilton Beach customer support or consult the user manual for guidance. If you have used particularly toxic chemicals and are worried about potential health hazards, it's advisable to seek advice from a professional or poison control center.
