Product review (5 stars): Clean Up is a SNAP
This simple oven liner is a time saver!  Anything that is baked and runs over, falls down on the liner and cleans up with just a damp cloth.  And, they last for years.  The previous one I had in the over was there for over 7 years.  I highly recommend this liner to everyone who does any baking.  It's a true time saver
