The stabilizer is there for a reason.

I know it sounds like sacrilege to some, but there is nothing wrong with wiping the excess stabilizer off the film to avoid those white spots from forming. Ideally, the stabilizer should not impart those white spots to begin with, so maybe that's user- or product-error that needs to be corrected. When I develop C41 at home, I have used many different types of chemistry, and I have given a final rinse in the stabilizer, followed by wiping the entire length of the film, on both sides, with an extremely soft and supple rubber edge. Negatives are squeaky clean and not a single scratch.

But use the stabilizer as directed, or that gelatin and the dyes will become food for bacteria and other critters. It's just a matter of time.
