A Research-Driven Fretboard Conditioning Formula
Fine Nourishing Oil No.1 is the result of material research focused on unfinished hardwoods used in fretboards. The formulation prioritizes penetration control, oxidation resistance, and long-term performance, ensuring consistent results without altering the natural behavior or feel of the wood.
Most fretboard oils rely on generic cosmetic formulas or aggressive solvents designed for short-term results. Fine Nourishing Oil No.1 was developed through material research, workshop testing, and long-term observation on high-end instruments.
Its formulation focuses on:
- controlled molecular weight distribution for penetration without migration,
- oxidation resistance to prevent long-term residue,
- compatibility with dense, unfinished hardwoods used in professional instruments.
This approach ensures consistent performance over time rather than immediate cosmetic effect.
Controlled Nourishment
Designed to deliver conditioning evenly into dense hardwoods, allowing the wood to absorb what it needs without oversaturation. This controlled approach avoids surface films and ensures the fretboard remains balanced, responsive, and dry to the touch
Wood Compatibility
Specifically developed for unfinished fretboard woods such as ebony, rosewood, and pau ferro. The formulation respects the natural structure of these materials and remains safe for use on both modern and vintage instruments
Long-Term Stability
Formulated to resist oxidation and chemical degradation over time. Unlike traditional oils that can become sticky or harden with age, this blend maintains consistent behavior, even with repeated maintenance over long periods
Clean, Natural Feel
Leaves no greasy residue or artificial gloss. After application, the fretboard retains its original tactile response, with a subtle woody note present only during use, fading naturally once absorbed.
Thoughtful Formulation, Measurable Results
Rather than creating an artificial surface sheen, the oil conditions the wood internally and evenly. Once absorbed, the fretboard retains its natural tactile response — smooth, dry, and comfortable under the fingers. Conditioning remains effective over time, reducing the need for frequent reapplication and avoiding saturation of the wood.
Many traditional fretboard products rely on petroleum-based carriers or citrus oils that evaporate quickly, leave residue, or interact unpredictably with wood and finishes. Fine Nourishing Oil No.1 avoids these components entirely. Its formulation is free from petroleum derivatives, lemon oil, and aggressive solvents, ensuring clean absorption and a residue-free surface even after repeated use.
The formulation is based on carefully selected natural oils, chosen for their stability, compatibility with dense hardwoods, and resistance to oxidation. These oils provide controlled conditioning without breaking down, polymerizing, or becoming sticky over time. The result is a predictable, consistent performance suited for long-term instrument care.
Designed for use on common fretboard woods such as ebony, rosewood, pau ferro, and similar materials, the oil is also safe when applied carefully around finished surfaces. It does not attack lacquers, polyurethanes, or modern finishes, making it suitable for both contemporary and vintage instruments when used as directed.
Designed and Used in Our Workshop
This oil is not a rebranded accessory. It is developed, tested, and used daily in the Belforti workshop on our own instruments. It meets the same standards we apply to materials, finishes, and setups — because it is part of our instrument ecosystem, not an afterthought.
