I agree that steam / distilled water is the ideal rinse. Steam is another source for distilled water. It gets applied without a brush or other applicator so there's nothing to contaminate the clean water.
For actual cleaning, I use the DiscDoctor system that's designed for vacuum record cleaning machines like the HW-16.5. I haven't found anything that is better, and the DD brushes seem to be very good.
