Even with careful use, a classical guitar may gradually change in appearance or respond to unstable storage conditions. Have a close look at your guitar regularly and be attentive to changes. If your instrument is suffering from its environment, it will let you know.

Be mindful when touching your instrument with greasy or unwashed hands — any skin contact is a small attack on the varnish. Of course, a guitar is made to be played, but taking a few precautions helps preserve its beauty: wash your hands before playing, wear long sleeves, and avoid unnecessary direct skin contact with the body of the instrument.

A good habit to adopt is wiping down your strings briefly after each playing session. This small action significantly extends their lifespan and helps maintain a consistent, comfortable feel under your fingers.

Most importantly, clean strings are essential for keeping your instrument in tune. Corrosion, sweat, and dust can affect the uniformity of the strings and interfere with accurate tuning across the entire fingerboard.

Got a guitar with a shellac (French polish) finish? Here's a simple trick: take a clean microfibre cloth and gently breathe on the surface to create a light mist. Then softly rub to remove fingerprints, sweat, and grease. That's usually all it takes — no products needed.

Your guitar can safely stay outside its case, as long as the surrounding environment maintains 42–55% humidity and a temperature between 18–25°C. Keep in mind that humidity levels can still fluctuate inside the case, especially during seasonal changes.
