Freehub maintenance

[bobg]

Just been messing with a spare back wheel and found that although the freehub worked properly it has a tendency to "grate" a bit. I've been reading all the various posts on problems with using the "wrong" lub resulting in non operational pawls etc so I thought I'd check the very handy Park Tool site advice. http://www.parktool.com/repair/readhowto.asp?id=45
They recomend freehub removal, flushing with solvent, allowing to dry and applying a "liquid lubricant" Any recommendations for an appropriate lube please? Interestingly a lot of online advice suggests dont wash with solvent and relube at all. I'd be interested in what you all think. Ta
