Always thought that old trick for stuck seatposts was a myth
Had a steel frame with an aluminum post that was totally frozen, the usual heat and penetrating oil did nothing. A guy at the shop told me to try a 50/50 mix of automatic transmission fluid and acetone, let it sit for two full days, and then use a long breaker bar. I was sure it was just another old tale, but after 48 hours it broke free with a solid crack. The mix really does creep better than anything off the shelf. What's your go-to for a post that won't budget?

Honestly thought that was just a myth too.

Oh man, I wish it was a myth! I learned the hard way last year. Just check the seals on anything you buy, saves a huge headache later.

That mix is seriously the best trick in the book for a truly stuck post. Letting it soak for a full two days is key, the patience really pays off. For anything less than totally frozen, a good quality penetrating oil and some careful heat with a heat gun on the seat tube can work. It's all about giving the stuff enough time to actually creep into the threads.
