Since this topic has risen to the top again, I'll ask: does winter salt cause this problem as well? I used DT Swiss spokes when building the rear wheel of my winter bike, but use a cheapie MTB front wheel so that I can sacrifice its brake track to the elements. Would a careful application of Frame Saver or some other kind of waxy oil (just to the spokes) be a good preventative measure, or not worth doing?

Thanks.
