Anodized pans? Cleaning?

Question

Hoping SA would clear some controversy.

I was told that it's bad practice to put anodized non-stick pans in water immediately after cooking; as the water will cause it to degrade

I argue that it's harder to clean after the fat has solidified.

So does adding cold/hot water to hot non-stick anodized pan cause the surface to deteriorate and thus losing it's non-stick abilities?

Answer

Teflon-coated pans -- no, not a good idea, as the teflon and metal will contract differently when cooled, causing the layer to separate and flake off (eventually).

Hard-anodized aluminum: may cause warping if the pans aren't too thick, as aluminum isn't that mechanically strong, but the layer shouldn't separate, as it is strongly bonded to the aluminum, being produced from oxidation of the aluminum itself.

Pans that incorporate both teflon and hard-anodization: probably not a good idea to throw into water before cooling.

Indubitably, throwing a hot pan in water will deglaze the grease quite effectively, but if a teflon layer is involved, you are inviting trouble.
