So what do you use? What’s your routine?  This is what I tend to use - Smith polish in my Smith bass as intended - I tried to get the partner wax for the untreated Morado fingerboard but can’t find it in the UK.  Sadowsky said he uses the Planet Waves Hydrate on Morado so I’m going to give it a try next time I re-string.  My Wingbass is a Tung Oil finish and only needs a wipe with a damp rag so that’s easy.  The Vigier has a very worn lacquer finish which has gone satin in places.
