Question:

Why is my baking sheet turning my paper towel gray when I grease it?

While making cookies, my wife was greasing an aluminum cookie sheet (that she had just washed) and noticed that something silver/gray was wiping off onto her paper towelIs this unhealthy (I'm assuming yes)? Should we throw this sheet away (I'm assuming yes)?

yeah, you are pulling aluminum from the sheet onto the paper towelI use aluminum pans at work as they are durable and long lasting but I never put the food directly on the surfaceI use parchment paper always as a non-stick/no metal contact surfaceKeep in mind that nonstick Teflon is not much better because the coating will eventually leach into the food as wellIf you bake a lot or use the pans a lot you should invest in some parchment paper or silpat matsIf you don't know about either of these products just google the words.
