Lemon Oil For A Dry Fret board

I met Frank at the Great Northwoods Seminar in 1996. Extremely knowledgeable, very personable, and an excellent teacher.

Frank taught a class in compression fretting. He put a D-15 Martin from the fifties on the bench and started working. He never stopped working or talking except to answer a detailed question. He clamped the headstock to the bench, pulled the frets, then started putting frets of various tang widths to bring the neck into a back bow. (For those of you who do not know, vintage Martins do not have truss rods, just stiffening bars that sometimes take a set. Using frets with a thicker tang will "wedge" the fingerboard and the neck into a back bow.) A few went in, a few came back out. Fifteen minutes later he started dressing the frets. Frank used a jointer plane that he flattened on a surface plate. To the sole plate he attached PSA backed abrasives. He probably changed out the sheets forty or fifty times during the leveling. The entire job took him about an hour and fifteen minutes. Played like a dream.

One thing that I learned from him. He moved that Martin around the bench like it was nothing special. I asked him about that later. He told me that the guitar is just an object to be repaired. He held no special reverence for it. It is simply a workpiece. I adopted that attitude. The level of my work went up exponentially. He removed the fear from task.

By the way, those of you who worship at the altar of Dan Erlewine should take note. Dan and Frank trade tips all the time. They share a mutual respect for each other's skills.

Here’s what I’ve used on all fretboards for the last 10 years. It was in my grandmother’s stuff. It’s so old it doesn’t have a ZIP code on it. The price on the cap is 35c. Love this stuff. It’s fantastic. Cleans the guck off nicely and looks great. Frets don’t float up. You don’t need to use much. I’ve probably used maybe 4oz in that time on a dozen instruments or so. I don’t treat every string change.

I don’t really understand the notion that unfinished wood doesn’t need anything on it. Look at your deck. Look at your fence. Without treatment wood dries out and cracks. There’s nothing magic about the wood used for fretboards.

The bag of steel wool shown is about 20 years old. Carefully used, it actually does a lovely job of freshening up and crowning the frets. Little scratches on the wood if you look close but the improvement to the fretwork is certainly worth it.

This is what’s been working for me.

Just to be the latest...

1) Fretboards do not need to be oiled.
2) All it does is change the color temporarily.
3) I have two basses (Fender and Gibson) with rosewood fretboards that haven't been oiled in 40+ years, and have always been in very dry climates. No damage, no problem.
4) Excessive application of oil to a fretboard may encourage frets to come loose.

So if you do this, consider it to be entirely cosmetic and do it with extreme restraint. It serves no physical purpose.

I used the mineral oil very sparingly. Maybe 2 drops on a cloth and wiped the board down from one end to the other. Then I took a dry cloth and wiped the board down again to remove any excess. Looks like brand new. If I have to do this one or twice a year, it will be no problem.
 
I didn't read all 6 pages, but I just oiled up a very dry board on a recent acquisition with extra virgin olive oil. I have a can of boiled linseed oil in the garage, but didn't want to go out there for this quick application.
If an oil is safe to eat, it's safe enough to apply to a fingerboard without fear of unseating frets, messing up a finish... Plus, EVOO always on hand at my house.
I apply a very thin layer and wipe it off after about 30 seconds. Done. Won't do it again for years.

I think any oil mentioned in this thread has the potential to unseat frets; it depends on the quantity applied and how it is applied.
 
Oil does not cause frets to lift. Oil can and does wick into the kerf where the fret tang resides. It readily soaks into the end grain. When that happens frequently the wood can become soft or "punky." When that happens the fret is no longer held tightly and can lift.

The quantity of oil applied is only a contributory factor. Frequency is the main culprit.

I use the Dunlop 65 lemon oil on instruments with ebony finger boards; linseed oil on every thing else that isn't sealed or synthetic. I know that lots of people say that you don't need to use anything, but they always seem to be living someplace where there's actual humidity 90% of the time. Which isn't the case here in Las Vegas (can you say "Mojave Desert"?). Just a little of either, about once a year, works fine for me. Why the lemon oil? Because the list price for my Alembic Epic is $7,000, and "a good lemon oil" is what they say to use - right there in the owner's manual. I figure that, since they made the thing, they should know best. So, lemon oil it is...:)

I live in Mississippi where the humidity is always above 90% but the fretboard looked ashy when I got it a couple of years ago. I have no idea where my bass come from as it was used . I have never had to do anything to a fretboard on any other bass I have ever owned. A little mineral oil did the trick. I can only imagine living with low humidity. I think my sinuses would love that.
