I hear you on the mallet—one minute you’re feeling like a pro, next thing you know, you’re crawling under the fridge for a rogue washer. I’ve had better luck with PB Blaster too, but sometimes I’ll wrap a rag soaked in hot vinegar around the stem for a bit. Seems to help break up the crud without as much drama. Just gotta watch out for that lingering vinegar smell...
That vinegar trick is clever, but man, I can’t get past the smell. Last time I tried it, my whole kitchen smelled like a salad for two days. I’m more of a PB Blaster loyalist—let it sit, give it a little tap with a small hammer (not a mallet, learned that the hard way...), and usually it gives up eventually. Just gotta be patient and not force anything or you’ll end up with a busted stem and a bigger headache.
PB Blaster’s been my go-to for years, too. I tried the vinegar thing once and my wife threatened to ban me from the kitchen—couldn’t get that tangy smell out for ages. I’ve had luck with a little heat sometimes, just a hair dryer aimed at the threads, but I always worry about damaging old plumbing. Anyone ever try those freeze-off sprays? Curious if they actually work or just another gimmick.

I’ve wondered about those too. Does the cold really shrink the metal enough to make a difference, or is it just marketing hype? Also, is there any risk of cracking old pipes if they’re already kind of brittle?
I’ve tried those sprays a couple times on stubborn bolts, and honestly, the results were mixed. The cold does contract the metal a bit, but if the pipe’s already fragile or corroded, I’d be careful—rapid temp changes can make old metal crack. Sometimes penetrating oil and patience work better, especially on older plumbing.
