Question: I have a new GE cafe series electric oven--no exposed coils or vents.  Can I place this mat on the oven floor?
Document: The online product description says it is suitable for gas and electric ovens, but on reading the instructions on the box, I learned that the liner cannot be placed on the bottom of a gas oven. Instead you must situate it on one of the wire shelves and cut it so that it doesn't block the bottom heat vents. Although it is not a major inconvenience to place it on the wire shelf, I can't just place it on the oven bottom and forget it, like I had expected.
I'm not a slob in the kitchen but this is a great idea. I have a new oven and I like keeping it that way. It would be even better if you put it on the floor of the oven instead of the lower shelf.
When I moved to my new home the first thing I did was order this Non-Stick Oven Liner so my oven floor would stay as nice as when I moved in. I had lived in my previous house for 3 years and was so nice to just remove the old liner and do a little wiping off around the door and have an oven that looked like new and ready for my house to sell. Clean up is so easy when something spills over in the oven and from the normal oven splattering.
I have used one of these for over a year now in my electric oven. It is great. I am always having pies bubble over or sweet potatoes oozing. Then, I would have a burned glob on the bottom of my oven which required running the cleaning cycle. Now, I just slip out the mat, wash it off - the burned residue washes away very easily. I know I could put something under my pies or other foods but I never seemed to remember.
Read the instructions! It's easy to install incorrectly. I had to trim the liner to install properly. However, that is a simple task with a scissors. Once in place, it just lies them unobtrusively and does its job.
Terrible item totally melted in my new oven I threw it away! Came with no instructions! What a waste of money
New house and ovens! I wanted to protect the ovens from the start! These are great! Easy to clean and wipe down when needed.
Purchased this thinking that it would go on the oven floor under the element. No, it just sits on the bottom shelf. I could have used aluminum foil for that. It should be made clear in the item description that it is not designed to go on the bottom of the oven, but on the shelf. I'm still going to try it, but am concerned that it will affect heat circulation throughout the oven and therefore the cooking time of food. Will food not cook sufficiently on the bottom?
We like it, the only think I don't understand, why it can not be placed on the bottom of the (electric) oven. We did just that and it works better, than on the lowest rack as recomanded.
This item is truly easy to clean vs. the bottom of the oven. I wish there was a product that could go under the element on my electric oven instead of using the bottom rack of the oven.
