One way is in the oven, but im always worried about the stopper melting or the label.
I like to put a little water in a frying pan, bring it to a simmer and sit the bottle upright, i like to vent it with a needle tip, Make sure that needle tip isn't down in the oil or the oil will start to come up through it.
Have a glass of water sitting on the side of the stove. Because you're gonna have to frequently add a couple of splashes. Every few minutes I grab it with a cloth and shake it up and then put it back into the water. Usually takes about fifteen to twenty minutes total depending on how bad it's crashed. I haven't had tons of crash gear before, but i've used this method like three or four times and it does work
