Every now and then, you'll want to give your guitar's fretboard a clean to keep it playing smoothly - MusicNomad's Fretboard F-One Oil is one option for a dirt-free 'board.
It avoids commonly used 'lemon' oil and works on all unfinished rosewood, ebony and maple fretboards.
Although its mixture of ultra-refined tree and seed oils can make your guitar smell like a garden centre up close, F-One Oil cleans and protects your 'board.
It certainly brought silky playability back to the guitars we tested it on, and since you only need to use a tiny bit each time, one bottle will last ages, too.
