Why Cant I

[dombanks]

why cant i put a set of hard anodised aluminuim pans in a dishwasher?

apparently according to the leaflet "hard anodized cookware is scratch resistant, non reactive (NSF approved), non porous, and two times harder than stainless steel"

but i cant put it in the dish washer, is it just the tablet might scratch them?

In general, dishwashers are not a safe environment for anodized aluminum cookware. The reason for this is both the nature of automatic dishwasher detergents and the nature of the automatic dishwasher process.

Aluminum is a very reactive metal, and the surface is rendered less active by the process of anodization. However, automatic dishwasher detergents are caustic and will attack the aluminum.

But the dishwasher environment itself is hazardous to aluminum! Many consumers improperly mix different types of metals in their automatic dishwasher. They may have silver, stainless steel, and aluminum present in a single wash. Mixing different metals in water creates a battery. One metal dissolves another while generating a flow of electrons! Unfortunately, aluminum is usually the metal that gets dissolved, resulting in pitting and discoloration of the aluminum cookware

All respect to the Materials and Corrosion expert . Aluminium once it has an oxide or anodised protective layer is fairly unreactive but a little scratch or opening to the clean aluminium beneath lets the ions dance about and mega corrosion sets in as eloquently detailed above.

Tigger, best make sure you only put non aluminum engine/car parts in the dishwasher in future.
