Rust!

[LogansMommy]

Is it safe to cook with a baking sheet that has rust on it?

Good question - I have one w/rust, but I just put aluminum foil on top.

can't you just scrub it off? That is what I do with my cast iron if it gets a rust spot.

Google "Removing Rust From Baking Pans"
A bunch of stuff comes up. Guess you can use a potato or cooking oil.
It is not safe to cook with the rust, so I myself clean the pan and dry it and then put tin foil over it.
The rust can come back.
Stainless steel or glass pans are better.

I agree with the above. I would not cook with rust, I would clean it off or use aluminum foil.

I nearly always put parchment paper in my pans. It peals off cakes with no cracking, it isn't harmful if someone gets a tine bit of it, it makes clean up SO easy and your items come right out.

I even put it under my racks when I bake bacon.
Depending on what your cooking it could be better then foil

I agree with the parchment if you can't get rid of it.

I have a pan with rust on it, I just line it w/ aluminum foil before using it, works fine.
