Had a seized seatpost that wouldn't move. Remembered the ammonia trick and it slid right out.

That ammonia trick is pure chemistry. It dissolves the aluminum oxide corrosion that locks the seatpost in place. Just don't use it on a carbon frame, it's a bad idea. Works way better than just yanking on it and making a mess.

Let it sit for a while before trying to twist.
