Guitar String Derusting & Anti-Rust Care Pen

Keep Your Guitar Strings Clean, Smooth and Protected

This Guitar Strings Derusting Brush Pen is designed for players who want consistent tone, smooth feel and reliable string performance. Combining a cleaning brush, eraser-style scrubber and string care oil in one compact tool, it helps remove rust and grime while adding a protective anti-corrosion layer to your strings. The pen-style design makes application controlled and tidy, so you can maintain your instrument at home, in the studio or on stage without mess.

The elongated plastic body sits comfortably in the hand, allowing you to guide the built-in brush and cleaning pad precisely along each string. As you work, the cleaning surface lifts oxidation, sweat residue and dirt, while the integrated oil applies a thin, even film to help reduce friction and protect the metal from moisture. This supports longer string life and more stable sound, especially for players who practice or perform frequently.

Suitable for a wide range of stringed instruments, this tool can be used on electric guitar, acoustic guitar, classical guitar, bass (with care), violin, viola, cello, zither and other metal-string instruments. Its compact size fits easily into a gig bag, case pocket or accessory pouch, making it a practical addition to any regular maintenance routine.
