Unique and simple patented proprietary solution for any stringed instruments' fingerboard that hydrates the wood and removes grime and oxidation from the frets in one simple application. The result is a clean hydrated fingerboard with shiny frets and a satin smooth finish protecting against sweat, acids, metal corrosion, and string abrasion. It helps to prevent cracking and splitting of the fingerboard and bring back like-new lustre to the frets. This solution contains no harmful chemicals, is prop65 compliant, cruelty free and vegan. It is air-travel safe world-wide and only contains food grade products and is free of lemon oil. Its re-sealable zippered package has equal dimensions as a pack of guitar strings with included hang-tag. The one-piece applicator cloth can be used multiple times.
