Sounds like your foil melted to the bottom of your stove. Try scraping off as much as you can with a plastic scraper and then put a mix of vinegar and baking soda over top the area. Let sit for a while and then try scraping again.

I'd try putting a large glass cooking pan on the lowest rack of the oven and fill it 1/2 full with warm water pushing it as far back to the back of the oven as possible. Turn your oven on AT 300 degrees and set a kitchen timer for 40 minutes. Take care when you open the oven door as there will be steam, but you might be able to carefully remove the aluminum foil from the oven bottom. Don't remove the baking pan until the water is cool to avoid scalding. Hope this helps.

Baking soda and vinegar. I swear by it.

My wife, trying to protect her new double oven, put foil in the top and bottom oven. Needless to say, the foil stuck to both. In desperation, she self cleaned the top oven which only made it worse. So, thanks to this forum, we tried Easy Off first with not great results so we tried The Works toilet bowl cleaner. Thank goodness, it worked. We used a tooth brush and several small applications on both ovens. The bottom was easier to get off since she didn’t try the self cleaning method on the bottom. There was some discoloring on the top and bottom ovens but not anything unsightly like the foil being stuck to the bottom. Thanks for the suggestion and hope this helps others in the same predicament.

Don't waste your money on the sodium based oven cleaners. I spent $13 on Amazon to purchase a can that was worthless in trying to clean off the melted aluminum on the bottom of my oven. Plus they are not recommended for use in a self-cleaning oven.

Pour some baking soda into a bowl. You want to slowly add a small amount of white vinegar in a bowl. Stir it in until the mixture reaches a thick paste-like consistency. The two ingredients will bubble and fizz as they mix, but you want the baking soda to neutralize vinegar. Do not use white vinegar alone as this can cause damage to your oven and even be dangerous.

Apply the paste to the melted foil and let it set in overnight. Then wipe off the paste. It may have dried out overnight, but this is normal. Place a very wet cotton towel over the foil. Do not use a synthetic fiber towel such as rayon or polyester because they are more sensitive to heat. The towel needs to be very wet because if it is dry, it could possibly cause a fire.

Turn the oven to 200 degrees Fahrenheit for 30 minutes and close the oven door. The water will produce steam, causing the foil to loosen and become unstuck. Once the oven has cooled off, you can gently peel and remove the foil pieces. They should come off relatively easily.

Mogie - We have tried both of those things you suggest, and no luck. We just remodeled our entire kitchen, took down walls, made a very significant upgrade, bought a wall-oven for the first time, and this happened, literally the first time we ever used it, cooking frozen pizza! We're devastated.

Have not yet tried The Works toilet bowl cleaner and a toothbrush (sigh). Was trying to avoid the discoloration, but I guess that's next. And if that doesn't work, and I guess we have aluminum foil on our oven floor for life.
