The lady at the hardware store swore you could clean a rusty cast iron pan with a single lemon

I was at Ace Hardware in St. Louis last Saturday picking up some scrub pads, and this older woman behind me in line starts telling me her grandma's one trick. She said you just cut a lemon in half, rub it all over the rust, and let it sit 10 minutes - no soap, no scrubbing. I tried it on my old Lodge skillet when I got home, and honestly it took the rust off but left this weird sticky residue that took another 20 minutes to rinse out. Has anyone else fallen for a 'one ingredient' fix that was way more work than just using steel wool?

Did the lady mention anything about seasoning the pan afterward, or was she just focused on the rust removal part? That sticky residue sounds like lemon juice reacting with the iron in a way that leaves a film behind. Have you tried a vinegar soak instead, or do you prefer sticking with steel wool for your cast iron?

Dude, you're overcomplicating this whole thing. @parkerp80, you say seasoning is the next step, but who cares about seasoning when the rust is still flaking off into your food? I've salvaged two rusty pans from yard sales with nothing but steel wool and elbow grease, then cooked bacon in them same day. No vinegar, no fancy acid soaks. That sticky film people complain about is usually just leftover oil or carbon, not some weird lemon juice chemical reaction. People spend way too much time babying cast iron when it's literally just a hunk of metal designed to sit in campfires.

Notice this same thing happens with a lot of kitchen tools people try to rescue from rust. Everyone goes straight for the strongest acid or abrasive they can find without thinking about what comes next. It's like fixing a flat tire but ignoring the fact the spare is also low on air.
