That alcohol should evap off very quickly. I let mine sit for ten minutes or so and have never tasted the nasty rubbing alcohol taste. I also wipe mine with a paper towel afterwards though.
The other thing to try, right after soaking it for a bit is pressing a sewing pin in the holes and jiggling around a little bit to free up any gunk in there. I do that once a week or so with my autos and it makes a ginormous (technical term) difference.
