I bought 9' x 13' disposable pans years ago. Just started using them to make brownies and it turns out that the labels were stuck to the bottom of the pans with some kind of clear glue and it leaves a thin clear film when I remove the labels.
Any thoughts on how to salvage these pans? I was thinking putting parchment paper or aluminum foil on the bottom of the pans. Does that sound like it would work?
