The Jim Dunlop Formula 65 Fretboard Ultimate Lemon Oil Polish is a popular fretboard conditioner

and cleaner made in the USA, designed to maintain the health and appearance of guitar fretboards,

particularly those made of darker woods like rosewood and ebony. Here are some key points about it:

Fretboard Conditioner: It helps in cleaning and conditioning the fretboard, removing grime, dirt, and

oil that accumulate over time from regular playing.

Lemon Oil: This product is made with lemon oil, which not only cleans but also moisturizes the wood,

preventing it from drying out and cracking. It restores the natural luster and ensures longevity.

Non-Greasy Formula: The oil is designed to be non-greasy, so it doesn’t leave a residue behind that

could affect playability.

Use on Unfinished Fretboards: It's important to note that this product is meant for use on unfinished

fretboards like rosewood, ebony, and pau ferro. It shouldn't be used on maple fretboards, which are

usually finished.

If you're maintaining a guitar with an unfinished fretboard, this is an ideal product to keep it in top condition.
