To keep your guitar in good condition, focus on regular cleaning, proper storage, and addressing humidity. Wipe down your guitar after each playing session, especially the strings and fretboard, and consider using a guitar-specific cleaner and polish. Store your guitar in a case, preferably a hard case, to protect it from physical damage and fluctuations in temperature and humidity. Acoustic guitars, in particular, are sensitive to humidity, so maintain a humidity range of 45% to 55%
