When I first got mine I used spray oil. Then tested them without using it. No difference at all. So I stopped using the spray. I’m thinking that maybe at some point way down the line when they’re showing some wear, I’ll go back to spraying them.
(Over the years I’ve had several USA sheet pans and it took quite a long time and a lot of roasted vegetables and other things before I needed to use parchment paper.)
