MusicNomad MN120 String Fuel Refill

Refill Your String Fuel Applicator

The MusicNomad MN120 String Fuel Refill is a 14.79 mL bottle of hybrid mineral oil blend designed to top up the MN109 String Fuel Applicator. Once the applicator pad dries out from regular use, this refill restores cleaning and lubricating power so strings stay slick, sound fresh, and resist corrosion longer. The specially designed dropper makes refueling quick and mess-free, and one bottle refuels the applicator a minimum of two times.

Why Players Keep a Refill on Hand

The silicone-free formula cleans and lubricates acoustic and electric guitar strings, reducing finger squeaks during play and helping strings last longer between changes. Unfinished fretboard wood is also conditioned safely without harming any finish. For anyone who already owns the MN109 applicator, a single bottle refills it at least twice — far cheaper than replacing the applicator outright.
