Yep been using since I purchased guitars with rosewood fingerboards, and it has been discussed on jemsite alot.

By far the best product for rosewood. Bore oil, fret doctor = same thing..

fret doctor is the way to go...

Can you point me to a good brand of bore oil? I've always used lemon oil once every 6 months on my rosewood (and ebony), but this bore oil sounds interesting...

I've been using Fret Doctor, only because everybody was raving about it so it's more selling point than I think it's any better.

i havent heard of any other bore oil brand, so untill its pointed out, its all I know....

I have purchased from this site and its all legit..

The best stuff I have found is "Guitar Honey" by Gerlitz, very smooth, not too greasy, and lubricates/shines the fretboard admirably !

Too bad they don't ship overseas and don't seem to be distributed in Europe (they don't know on what money they are missing out !)

Taking a couple of bottles home everytime I am in California - I definetaly suggest you guys in the US check it out and give it a try !

Cheers :-)

Duck wax, isnt that better or worse? i use lemon oil too,,

I make quite a few guitars, and i also use lemon oil to get the fretboard nice slick and oily. tip: only use a few drops onto a cotton pad or something similar, wipe on .... wait a few minutes and wipe off with some elbow grease put into it, if the board is still oily wipe off again untill slightly damp.
like i say i use it on rosewood and love the results, but to much can cause affects in the wood and some fretbuzz even so dont go overboard.

I didn't realize there were so many approaches and controversies! For what it's worth, I've always had good luck with plain lemon oil marketed for furniture on my rosewood boards--I apply a tiny bit, let it soak for a few minutes, and rub off the excess.

And I'm a fan of tung oil on necks, but I suppose that's a topic covered in other threads...

I have used olive oil and teak oil, to me they both make the guitars feel better and keep the wood from drying out so they are OK.

Cant see any great need for lemon oil, I have a Yamaha APX SPL I thats 20 years old, I dont play it much now but the wood is still in great condition. Years ago I just used to use whatever cooking oil was in the kitchen and it looks fine now.
