Okay, so if glass is too heavy, then I’m guessing cast iron is right out.

Any pan is going to get that sticky grease. Fats (including oils) polymerize at high heat. That’s how people intentionally season cast iron cookware, but you’re seeing it where you don’t want it. The easiest thing to do is accept that you are getting an extra coating of ‘protection’. Otherwise, maybe see if this link’s boill-with-vinegar suggestion helps? https://food52.com/blog/25458-how-to-care-for-nonstick-pans

I clean my cast iron pans with salt and kitchen paper over medium heat. It’ll clean residue without removing the seasoning.

I don’t use nonstick for roasting, because thats an issue because if you want them to be perfectly cleaned you need to use steel wool. Stainless steel is the best. If you’re not concerned about the non stick because there is sticky stuff stuck, use steel wool.

Also, roasting pans are generally acceptable to have some baked in grease, and unless you’re in a 3☆ Michelin restaurant, its OK.

I’ve had success filling such pans with water and a single drop of dish soap then boiling it

Don’t use nonstick pans for roasting. The Teflon coating doesn’t like high temperatures and will flake off. Use a stainless steel pan for that kinda thing. Cast iron works too, but requires more babying.

But also yeah, barkeeper’s friend works well at cleaning the surface.

I use Barkeeper’s Friend. It works great on most metal surfaces.

All my favorite cookware are fucking heavy, so on that front I don’t have much advice. One thing I can say though is to experiment with lowering your cooking temperature. I know sometimes we can be in a hurry and we crank it up, but often we could have gotten the same result with a lower setting and a tiny bit more patience. This can make a huge difference with how hard the residue gets stuck. Finally, the nonstick film unfortunately gets worn out after a while and at that point everything will stick non stop. At that point there’s not much to be done but replacing the pan sadly.

Sorry to add this so late, but TV news just told me about an increase in “Teflon Flu”. Remembering you had non-stick pans, I wanted to find a link. In a quick check, the majority of the links seemed to come from somewhat suspicious sources such as NYPost and Daily Mail rather than a .gov or .edu.

I’m not saying this is a legitimate thing, but if anyone wants a starting point, you could try here: https://www.womenshealthmag.com/health/a61623919/teflon-flu-symptoms/
