What cleansers are safe to use in cleaning a deep fryer?

When cleaning a deep fryer, it is best to use mild, non-toxic cleaners that are safe for food contact surfaces. A solution of warm water and dish soap is effective for general cleaning, while vinegar can help remove grease and odors. Avoid harsh chemicals, abrasive cleaners, or anything containing chlorine, as these can leave harmful residues. Always ensure to rinse thoroughly after cleaning to prevent any cleaner from contaminating the oil or food.
