Fretboard conditioner is a specialized product designed to clean and maintain the wood of a guitar's fretboard. It helps to remove dirt, grime, and oils that accumulate from regular playing, ensuring the fretboard remains in good condition. This conditioner often contains natural oils that nourish the wood, preventing it from drying out and cracking. Using fretboard conditioner is essential for guitar care, especially for instruments with rosewood or ebony fretboards. Regular application can enhance the appearance of the wood and improve playability. It is typically applied with a soft cloth and should be used sparingly to avoid over-saturation.
