Is the oven liner the same material as the StoveGuard? Can I put it on the oven floor? What if it is too large for my oven rack?Updated a year ago

Yes. The oven liner is the same material as the StoveGuard. It is for use on the RACK only and NOT the oven floor. It should not be used on the oven floor as this may cause damage to both the oven liner as well as your oven! The oven liner is one size and can be cut with scissors to fit the inside of your stove on the rack if need be, however this may cause the edges of the oven liner to fray slightly.
