First?........Personally, I would "never" use lemon oil. It drys out the wood. Good ole woodwind oil, or bore oil is excellent. It really adds lustre to the wood.
Second? I would go to Rich Harris' site, IbanezRules. He has an awesome tutorial with pics on cleaning fretboards.............well.........the whole guitar.
Of course............this is gonna start one of those lemon oil arguments probrably.

But like I said..............its only "my" opinion
