... that's also the cleanest oven therm I've ever seen !!!!!
Oh yeah that's me, all about that shine, which is why the lid has a layer of grease forming that's about to fall off.
Did the oil thing to the face you mentioned the first time and it worked. Did it for the second cook and it did not, the face became cooked-on greasy and I had to scrub and scrape it off. Didn't bother doing it this time but will the next time I cook food right on the grate.
Or I could just buy new ones every few weeks.
