There's not a good way that I'm aware of. Only way I know is quite messy. I just use a commercial paint stripper, like Bix or Zip Strip. Use a brush to put it on, let sit for 15 minutes or so and wipe off. I use steel wool to wipe off the paint. It fills fast so will end up using a lot of it. Usually need a second application. For that I use a finer steel wool. I do a polish with an even finer steel wool after that.
Because of the time, effort, smell and mess involved, I don't do it much.
