A large tupperware food storage container was inside of the oven, on the bottom, when the oven was turned on. It melted. Although it probably would have been easier to clean if it had been left to cool as a large mass, it seemed to be a good idea at the time to use a spatula and get as much of it out as possible while still relatively molten.

Now there is a thin layer of plastic on the bottom panel. I can get most of it off with a razor scraper. Is there a solvent that will get off the rest? What about using the self-cleaning function, which somehow doesn't seem like such a good idea given the nature of the fumes. I could bite the bullet and get a new one, but it's ~$75.

Any thoughts?

 

I agree that the self cleaning idea is not good. Since it's an oven, you might try using a torch and a long handle scraper to heat the surface and scrap as it melts (if it melts). Sorry best I can come up with.

 

You might try use liquid soap as a lubricant and a plastic scraper/putty knife and see if that will scrape it loose.

 

Heats not going to work.
Cover with ice and scrape off with a putty knife once it's cooled.

 

Since nobody else knows for sure--I'll add one more "might". The self-cleaning temperature reduces normal baked-on gunk to ash. A thin film of poly "might" also burn up to dust.

I can't think of any over-the-counter solvent that would dissolve polypropylene or polyethylene. Solvents are stored in such plastics

 

Try dry ice if water ice doesn't work. It may make the plastic brittle enough to scrape out.
