Can the non-stick coating be removed from cookware and still be useable?
I have an old but very useful baking sheet. It is heavy-gauge aluminum, and in reality having had it for so long it is unlikely that I would be allowed to replace it. Here is a photo to give any idea what I am facing.
My question is whether the remaining non-stick coating can be safely removed. At this point we are probably eating some of the coating so I think it would be better to do this if possible.
Best Answer
Removing it mechanically (sanding with waterproof P100 and then again P200, steel sponge, sand blasting, ...) will remove the coating and expose the pure shiny Aluminium.
The advantages of Aluminium are :
- light
- cheap
- conducts heat well.
The disadvantage of Aluminium is that it's a health risk if used improperly, so:
- Let it oxidise for a few weeks after you've removed the coating so that it becomes dull again: Al2O3 is much harder than Al and has less risk of leaching into your food.
- Use a lot of fat (oil, butter, ...) when using the baking sheet in the future
- Clean it with soft materials (sponge, cloth, ...)
- If it needs a thorough cleaning, you'll see the soapy water becoming grey: that's the Al2O3 being removed, so let it oxidise again for a few weeks.
If you take above precautions, you'll get another 25 years of usage out of it without it becoming a health risk!

Answer 2
Much simpler approach, far less work.
Purchase a Silpat® or any other "permanent parchment replacement" type product (I also have some sort of "cut to size youself" product that is not silicone, but serves the same purpose, though I don't recall the name.)
Slap it on top of the baking sheet. Cook. When your Pizza is done, slide it off the non-stick sheet and onto a cutting board before cutting.
Or you could use parchment, but that gets old fast, using a sheet every time you bake. But I guess you could leave it there while you cut the pizza.
