If my oven were reliable enough for actual use I'd pick one up!

We just melted an aluminium one to the bottom of our brand new oven this week.

i just use some plain aluminum foil, that seems to work, alternatively I put a baking sheet underneath anything i know will be messy

teflon isn't safe above ~ F 450.

But I keep my pizza stone in the oven always (great for thermal mass). If I cared (or remembered to, more accurately), I'd cover it with foil, but i just sort of scrape it clean before using it.

I tend to do most of my baking in my little DeLonghi convection toaster-oven, as it has a much more reliable temperature than the full-size ancient range left from previous tenants. Since, like most tabletop ovens, the heating fixtures at the bottom are not removable, I cut down a silicone baking liner to fit under them and just inside the pull out tray. Helps greatly with cleaning the bottom, I just pull out the tray, remove the liner to wash and dry the liner and then replace. For those who ask "why bother with a liner, just wash the tray" I will say that it is a good deal easier to clean anything sticky or burned-on off the silicone than it would be from the aluminum tray. Now if I could only figure out a good way to clean the rest of the inside...

Um, just use a cookie sheet underneath messy dishes. Why spend money on one more thing that you don't really need?

I'm with Charise... I just stick a cookie sheet under a pie that might spill over.

I also just keep my baking stone in the oven on the lowest rack. It works great as a drip tray. I have also seen liners that have melted in ovens. Beware!

I have used these for years! Being a renter, I like not having to worry about cleaning the oven before I move out. I have broiled chicken and baked pizzas at 500ºF (as hot as my current oven gets) and have never had a problem. I really enjoy baking so my oven does get used quite a bit. Yet, the liner I am currently using has been in my oven for 2 years and it's still in great shape. I also wrap my oven racks in aluminum foil to prevent them from getting too dirty. I replace the foil every few months as it tends to tear from pulling things in and out of there all the time.

On the topic of oven cleanliness. . . I also pause to spend money on another kitchen gadget, but I also am someone who avoids using chemical cleaners in my home. Any ideas on how to keep the oven less greasy and messy without resorting to the use of oven cleaner?

I'd suggest using the baking soda/salt/vinegar mixture to scrub the oven down every once in a while and using a baking sheet to catch spills while baking.

I'm with hahnanan. I take a few pieces of aluminum foil, lift the heating element (really ancient electric stove) and line the bottom with the foil making sure it goes up the sides a little. Then after I do something stupid like overfill a pie or tilt the pan when I take cookies out of the oven I just let it cool and take the foil out and put a new piece down.

I purchased an non-stick ovenliner. I later found out it was fiberglass and teflon coated. Please do not take the risk of using one of these liners. I lost my beloved white dove that I had for eight years and my parakeet. It was awful seeing them die. My daughter also was affected and went to the emergency rooms with respiratory problems. The oven got to hot for the liner and there were dangerous fumes given off. I agree--use a cookie sheet or foil!
