Yes - CLNSTR guitar string cleaner is designed to be safe for strings, frets, and fretboards. The cleaning material is firm enough to remove buildup but gentle enough to avoid wear or scratches when used as directed.

Yes. CLNSTR works on electric guitars, acoustic guitars, and bass guitars. It fits standard string spacing and is effective across all common setups.

Sprays and wipes mainly clean the surface.
CLNSTR wraps around the strings, cleaning the top, bottom, and sides in one motion—where most grime actually builds up.

Use CLNSTR as often as needed.

For gigging or daily players, cleaning after each session helps prevent sweat and oil buildup. Casual players can use it every few days or before storing their instrument to keep strings feeling smooth and sounding brighter.

CLNSTR helps extend string life, but it doesn’t replace restringing.

It removes grime and oils that cause strings to lose tone, allowing them to last longer between changes. When strings are worn, corroded, or heavily rusted, restringing is still recommended.

CLNSTR is safe to use on coated strings.

It’s designed to clean buildup without stripping protective coatings when used as directed, helping coated strings stay smooth and consistent for longer.
