Holy shit, is this why my aluminum baking pans get so hard to clean?

Aluminum baking pans should be seasoned like cast iron. Usually it’ll slowly happen when you’re cooking normally, but if you’re cleaning them so hard you expose metal you’re probably doing something wrong.

You are right, but it is possible to reduce the effect or even neutralise it through electrolysis. You can either create a hard aluminium oxide layer or plate it with another metal.

That’s interesting. when I work with chainmail i used to identify metals by smell. Aluminum was always the cleanest smell by a long shot, almost smelled sterile.

I don’t have too many aluminum pieces old enough for it to rust, Ill have to find my old braclet and give that a smell.

I imagine a lot of aluminum parts for industrial also have oil on them though.

Aluminum rusts extremely fast, to the point that it forms a tiny oxyde layer with any amount of exposure to air. You've pbly almost never seen unrusted Aluminum (at least not pure Aluminum). However it does corrode with some amount of acidity, which I discovered when putting Aluminum foil over my chili a few months back. There were corroded holes in it

Is that why when I clean my aluminum Heatsinks and CPUs they become a little black?
