Are the pans safe to eat from if they have turned black dishwasher?

Pans that have turned black in the dishwasher are not recommended to be eaten from, as they may be hazardous to your health. The blackening of the pans could be caused by a variety of factors, such as:

- Metal leaching: The high heat and detergent used in dishwashers can cause metal from the pans to leach into the food. This can be especially harmful if the pans are made of aluminum or copper, as these metals are known to be toxic in high doses.

- Chemical reaction: The detergent and other chemicals used in dishwashers can react with the metal of the pans, creating a black film that is not safe to ingest.

- Carbonization: Food residue that is left on the pans can carbonize when exposed to the high heat of the dishwasher, creating a black residue that can be harmful if eaten.

To ensure the safety of your cookware, it is best to avoid using pans that have turned black in the dishwasher. Instead, hand-wash these pans with a mild detergent and hot water, and avoid using harsh abrasives or chemical cleaners.
