      Thanks for your thoughts on this. I called 5 Star Chemicals and I'm waiting to hear back from a tech expert...In the meantime I took a closer look at the active ingredient list. It seems you are correct that phosphoric acid is soluble in alcohol but "dodecylbenzenesulfonic acid" (which is 15% of the active ingredients) is fully soluble in water though only PARTIALLY soluble in alcohol! So I'm thinking with the higher purity of vodka in comparison to wine (40% vs 12-14%) I'm realizing a precipitate. SHIT! So, I think in the end I'll be trying to filter it out? I'm hoping 0.5 micron filter pads will do the trick...prob going to run it through at least twice.

      I'll try to update when I hear back from the Star San tech.
