First and foremost, the new guitar player must learn the basics of keeping their guitar in good shape.
First of all, when you finish playing for the day, protect your guitar by placing it into a stiff case that fits the shape of your guitar. If you do not play as often as you might like, take the guitar out of its case occasionally in order to allow its porous, natural parts to "breathe." Avoid temperature extremes, as well as environments with fluctuating humidity levels. Heat can do serious damage to your guitar. If you have central heat, humidify the air in order to keep the wooden parts supple, keeping cracks and warps from forming. Even a pan of water left near a vent will help, should you not own a humidifier. Cracking and warping can occur most often in cheaper instruments, because guitar makers often shorten the wood's seasoning process in their cheaper lines. Beginning players, of course, are more likely to have an inexpensive instrument.
Wipe your strings after you play, using a duster or soft cloth. Exercise caution on the guitar’s wooden surfaces. Do not use polishes or other wood care products, since it is easy to ruin the delicate finish of the guitar, or cause the wood to absorb the product. You may, however, use a very slightly moistened cloth to remove grease spots, as well as other marks. Small cracks in the face or sides of the wood are common in fine guitars. Usually they are of little consequence until they attain considerable size. Before they get to that point, take your guitar to a skilled repairer, called a luthier. If, however, your instrument's fingerboard is warped, take your guitar immediately to an expert. The repair will be costly, but well worth the investment in the long run.
