That's great, but just a tip . . .
If you want a lasting "shine" on the fretboard, try bore oil (for woodwinds) instead of lemon oil.
I've used both and find I have to "lemon" the boards more often than with bore . . . the only downside is you don't get that citrus-y smell. ;-) J/K
If you MUST use lemon oil, I find that Old English is the best. (Just my preferance).
Just to claify, lemon oil isn't actually lemon oil, it's a petrolium based product, and that's why it dries out more quickly.
If you were to use actual lemon oil (juice, and I think someone on here did that) all you're going to do is dry the wood out totally . . . not good. :-)
