Product review (5 stars): Best oven liner for the price
With so many choices for oven liners we had a hard time deciding which to buy. So we went with the one that had the most reviews that were positive. After using one of the three we received, we had an overflow spill in the oven from a casserole that landed on the mat. After the over cooled we simply removed it, wiped it off with a wet soapy sponge and slipped it back in the bottom of the oven like new.  Having read so many reviews and complaints about oven liners that caught fire and damaged the oven finish, it is obvious that those people did not remove such spills onto the liner that then later caught fire or they had a gas oven that does not allow for such mats.  I would recommend this oven liner for its perfect fit without trimming, excellent functionality, and excellent low price.
