It’s not fun, but doable. I cut the stem so I could remove the fork from the bike and taped the area around the fork crown to protect the enamel. I then hung the fork upside down inside of a narrow container filled with a saturated solution of lye/Draino, outdoors, to avoid hydrogen gas mishaps. I had to replace the solution 3 or 4 times over the course of 5 days, and I helped it along by rinsing the fork clean and cutting notches in the remaining stem with a hacksaw. Eventually I was able to pull the remainder out with a pair of pliers.
As I mentioned, this is the second time I’ve had to do it, because I leave the bike outdoors most of the year and rainwater inevitably gets into the fork. I’m now planning to regrease it (with Marine Grease) once every month or so, so I don’t need to do it another time.
