Common Mistakes to Avoid

1. Using Excessive Cleaning Products

Reason: Harsh chemicals, polishes, or even excessive amounts of gentle cleaners can damage the guitar's finish, leaving it dull or stripping away protective layers.
Solution: Use only a slightly damp, soft cloth for cleaning, and avoid any chemical-based products unless specifically designed for acoustic guitar finishes.

2. Ignoring Humidity Changes

Reason: Fluctuations in humidity cause the wood to expand and contract, leading to cracks, warping, and buzzing strings. This is especially damaging to the guitar's sound quality.
Solution: Maintain a stable humidity level in your guitar's environment using a humidifier or dehumidifier, and store the guitar in a case designed to regulate humidity.
