Good point that about bi-carb. I wasn't proposing the OP scours the surface, simply to gently wipe it over.
And pmjos is also right that Lemon Oil will either float across the top, like and oil-slick on water, or do damage to a lacquered finish. The look of the bear wood becoming oiled-finish will also look odd.
Funny that nobody here has suggested lighter fluid. I know some folk swear by that for cleaning basses. I've not tried that, but it might lift of a load of old dirt and help a bit.

Didn't Jimi Hendrix use lighter fluid on his strat?
