oil? my fret boards are lubed with a mixture of sweat, blood and beer
At this point, I´m not sure if the fretboard is a part of the thread anymore.
To sum it up, rosewood is fat and hard and will stay that way with minimal care - but if you put it in a harsh environment like this,
it might dissolve in a river of lube, sweat and beer (band name anyone?) , along with other unmentionable natural and unnatural fluids
