Even that is not fool proof. Depends on what you cook in it.
Fried foods always stick. Spray with pan spray first.
Grandma’s big Chicken frying pan is 100 yrs old, still working for me just fine. I wipe low stick foods out with paper towels. Wash if necessary, lightly coat with veggie oil NOT COCONUT OIL, as you can’t get the temp up that high with out it smoking, in high oven heat for 30-45 mins depending on how hard I had to scrub it, when cool hit it with a tad of cooking spray and wipe off. Ready to use again. LEAVE THE BLACK PATINA ON IT!
You are right. Some foods will stick no matter what.
I try to use minimum heat to get by with. That helps.
