Excellent Product

This is an excellent way to clean and hydrate dark, natural-wood fretboards. The spray bottle is a bit messy, with lots of overspray to undesirable areas, so it is best to mask off the headstock, pickups, and body of the guitar before applying. Use a soft toothbrush to spread the product evenly and scrub the wood, particularly next to the frets, then remove the loosened dirt and excess product with a clean cloth. This contains petroleum distillates, so it offers the best possible cleaning and hydration without the (purported) undesirable side effects of lemon oil. Use sparingly....unlike money and horsepower, too much is worse than none at all.

great stuff

I feel a little dorky reviewing some fretboard treatment, but this is a really top notch product. It really does both clean and condition rosewood fretboards. It is not overly oily, but definitely provides some long-term oil hydration for the fingerboard. It seems like it also has some alcohol or some type of cleaner which evaporates, because it removes crud and dries somewhat, but the fingerboard remains slick and conditioned. This feeling lasts, and I would expect that using this every time you change strings should be enough.

I did not give it five stars because personally, I think the spray bottle stinks. It is very difficult to apply the product without getting overspray on places you might not want red tinted oil. A squeeze-typle bottle, like Gibson uses for some of its products, would be much better, and would allow you to apply it exactly where you want it without having to clean it off places that it should not be in the first place. Hopefully this is something that will change in the future.
