Many moons ago when i fisrt read about this possible issue it was mentioned that the main issues were with pans that had a pitted surface. This was primarily due to poor maintenance (not drying correctly) or if used for boiling betroot or other acidic produce. As a result of this we threw away 3 of our favourite pans but all pressure cookers ok just clean out quick and inspect after a beetroot boil. Beetroot barely cool enough before SWMBO tucks in.PS: I know many people will not use aluminium sauce pans thesedays, and insist on Stainless Steel but I cant remember why? Hopefully as I only use it occasionally, the risks if true, are kept to a minimum.
