I gotcha. Honestly, I mostly like deglazing in stainless steel because I can see what I'm doing. I can tell I've scraped the brown off. And I prefer deglazing in stainless to enameled, because it feels like less effort.

I'm not super careful about not using acidic things in cast iron, and I do deglaze in it on occasion, it's just a little harder imho. I can see how my original comment reads.
