Proper cleaning and maintenance extend a guitar’s lifespan and preserve playability. Early musicians used household materials, but specialized products now offer safer and more effective cleaning. Key brands include Dunlop (Formula 65 Cleaner & Polish), Music Nomad (Guitar Detailer), D’Addario (Hydrate Fingerboard Conditioner), and Gibson (Pump Polish). Fretboard conditioners prevent drying and cracking, while microfiber cloths safely remove dust and grime. String cleaners extend string life, and humidity control prevents warping. Regular maintenance ensures optimal performance, making it essential for all guitarists, from casual players to professionals.
