A tangential question, hopefully not taken as a hijack:
I have a fretless with ebony fretboard that also has small strips of maple as fretlines (kind of a cool feature, in that you can't tell there are any fretlines from the audience, as the lines are brown/wood colored and appear to blend into the fretboard from a short distance)...
Anywho, is there any known difference in the lemon oil cleaning method with regard to such small maple fretlines? I didn't think there would be, but thought I'd ask the experts.
