Cleaning tool for acoustic/electric guitar and bass guitar strings and fingerboard that removes wax, sweat and other dirt, extends the lifespan and maintain the tone of the strings. Tool is made of plastic and two flannel fabrics that are easy to remove, and is very simple to use: put the bottom part between the strings and the fingerboard and move up or down – it cleans the top and bottom of the strings in the same time, as well as frets. You can improve its effect by using liquid cleaner.
