Maintaining the cleanliness of your cuatro puertorriqueño fretboard is essential for optimal playability and prolonging the lifespan of your instrument. Here is a simple guide on how to clean it.

Materials: You will need a soft cloth, a toothbrush with soft bristles, and lemon oil (specifically designed for fretboards).

• Remove the Strings: Before you start cleaning, it's recommended to remove all the strings from the cuatro. This allows for easier access to the entire fretboard. 
• Wipe it Down: Use the soft cloth to wipe down the fretboard, removing any surface dirt and dust. Cleaning Solution: Apply a small amount of the guitar cleaner to the toothbrush. 
•  Dry the Fretboard: Once you've thoroughly cleaned the fretboard, use a dry cloth to wipe off any excess cleaning solution and let it dry completely. 
• Apply Lemon Oil: After drying, apply the lemon oil sparingly to the fretboard. This will help condition the wood and prevent it from drying out.  
• Let it Absorb: Allow the oil to absorb for approximately 15 minutes, then wipe away any excess with a clean cloth. 
• Restring the Cuatro: Once the fretboard is dry, you can restring your cuatro puertorriqueño.
