Product review (5 stars): These liners work well
We keep a pizza stone in the bottom of our gas oven to help keep the temperature more even.  The stone can't go through the oven's self-clean cycle, and it won't scrub clean.  It looks dripped-on in our nice, shiny oven.  Our solution is to cover the stone with something that does clean  or is disposable, and these liners work well.  We cut one of them to the size of the pizza stone and our oven looks nice and clean again.  It's too early to tell how the liner will clean, but if it doesn't work easily, we will cut up another liner.
