String cleaner for 4 or 5 string bass guitars with revolutionary design that provides 360° cleaning, removes oil, rust, sweat or dead skin and therefore extends the life of the strings and preserves their tone qualities. Cleaner is equipped with microfiber pads with porous sections for long-term low-maintenance use: after use, just run them under warm water with a drop of liquid soap or dishwashing liquid and gently massage the dirt out. Pads need to be dry before the use and no special liquid solution is necessary. Also, extended microfibers on the bottom of the device simultaneously clean the fingerboards (can be used on both fretted and fretless basses).
