Lena, I don't think there are any specific instructions. I do know they tell you not to spray them or anything, but I always spray mine (I shudder at the thought of lost cupcakes!). Also, make sure you put the silicone on a cookie sheet, it's easier to transport it!! Enjoy!
Took me a second to realize what you meant,lol. It's the collapsible bakeware,lol. I just have the sheets and haven't had much reason to use them. But I can see how you'd really want to use a spray on them,lol.
Let us know how it turns our, Lena? I'm curious myself.
