PUT ALUMINUM FOIL ON THE BOTTOM OF THE OVEN AND IT STUCK. HOW DO I GET IT OFF?

It says right in the owner's manual not to use aluminum foil on the bottom of the oven. Try to remove it with steel wool...

The foil can actually melt when exposed to the heat of the oven elements, so getting it off may be a real challenge as it could be bonded to the inside oven finish and it's best not to damage that.
I would try soaking it in oven cleaner and carefully continue to try to scrape it off.
Don't forget to follow the instructions on the cleaning container as it can be very caustic.

Hello Wendy;

My name is Peter. I am a retired field service appliance technician.

You can try to use a putty knife.

When your oven goes into the self cleaning model, you are burning off grease. The burning off of aluminum foil is nothing compared to burning off the grease.

You may see some small flame. But, this will soon pass. Your cleaning cycle can handle this without causing any damage.

With the older models of self-cleaning ovens one could put aluminum foil on the bottom tray of the oven, but with the newer models there is a warning (hidden in the last line) of your booklet for models of stoves where aluminum foil should 'not' be used! Even though print in small and many consumers are complaining regarding their stoves and melted aluminum stuck to the bottom tray of their oven (nothing will get it off) all manufacturer do 'not' cover this problem under warranty and thus, it will cost you $44 to buy a new tray. You unscrew the two screws to the bottom of the damaged tray of your oven and then install the new one and put back the screws. Letters of complaint should be written to the manufacturers to have them put this warning in clear bold print right on the front cover of the instruction brochure.

it most likely cant it fuse to the liner.y

How would I remove aluminum foil stuck to the bottom of a convection oven?

You may be able to get it opff with the oven hot. Whatever is holding it was liquid when hot before, so should at least loosen enough for you to remove it.

(Wear a professional n95 mask and rubber gloves). Use a straight razor and scrape off as much foil as possible. Get a hold of Mercuric or sulfuric acid. BE CAREFUL not to spill anywhere, work close to a stainless steal sink. Poor a little in a small glass container and bring over stove porcelain surface. Pour the acid onto the foil and wait 3-4 minutes, use paper towel to wipe off the acid, and then a soapy wet rag. Repeat process until all foil is dissolved. Then wash surface thoroughly and repeatedly with a soapy dish towel. Once complete run water in the sink for 5 minutes till any possible remaining accid is flushed from the sink. The foil is gone and the porcelain is preserved. Works great! (Don't breathe the fumes and ventelate the area or move the stove outside)

Use "The Works Toilet Bowl Cleaner" to dissolve the foil. *Caution* when the cleaner is applied to the foil a chemical reaction occurs releasing some harmful fumes so please use outside or in a well ventilated area. I just did this to a Frigidaire oven I bought from Lowes at a discounted price. The previous owners bought it, did not read the owners manual or just disregarded the warnings on using foil in the oven and thought they would line the bottom pan with foil to help make it easier to clean (Good idea, but don't try it on the hidden element ovens). With the heating element being hidden under the drip pan the heat is hot enough to melt the foil and fuse it to the pan. Now most of the pans on these ovens are removable by just a couple of screws and I strongly recommend removing the pan when doing this. Squirt some Works toilet bowl cleaner on it in a well ventilated area and watch it go to work. It took about 15 minutes for it to dissolve all the foil on my oven, then I rinsed it clean and reinstalled it in the oven. The pan does have a slight discoloration on it, not from the cleaner but from the foil being melted onto the pan, if you choose you can buff this out. Most of the modern ovens have the ceramic coated drip pans in them so the Works toilet bowl cleaner will not harm them, unless you have scratched the finish off. Works Toilet bowl cleaner contains a fair amount of hydrochloric acid which is what makes this work so well.
