The alcohol (IPA might be best) will certainly dissolve glycerin left over from soap. However, if you are in a hard water area, alcohol will not dissolve calcium deposits. My water in France is hard enough to knock nails in with. Everything that gets that water on it gets limescale. Shower cleaner works well to remove this but I would suggest using very carefully on the Zamak castings as it can corrode Zamak. Just a small amount on an old toothbrush and wash off quickly. Shower cleaner is fine on the plated brass parts.The other problem if you are always dipping in alcohol, is that it will dissolve any lubrication you put on the threads and you may find the adjustment getting very squeaky like mine did.
