The best way to clean your guitar is with a warm, damp cloth. This will remove harmful chemicals. Your guitar is coated in the highest-grade finish available and is sensitive. Any type of solvent, especially those found in plastic, vinyl and leather straps, will mar the finish, as will alcohol, citric acid, aftershave lotion, insect repellent, and a number of related substances. Perspiration can also damage your guitar, so keep it dry. We recommend wiping down your instrument and strings with a soft, dry cloth before storing to remove harmful skin oils. Products containing silicone should not be used.
Tuning Machine Maintenance
Tuning machines normally need very little care other than periodic lubrication. Enclosed machines, the type with a cover over the gears, are lubricated by the manufacturer, but the open type should be lubricated once or twice a year. Just put a little household petroleum jelly on the end of a toothpick and place the jelly in the gears. Be careful not to use too much because it attracts dust which can wear out the machines
Some types of machines are adjustable for ease of tuning. The open type can be made harder to turn by tightening the screw in the middle of the gear. Check this screw every time you replace the strings because it can work loose. Most enclosed machines have a screw in the end of the tuning knob that will make the machines harder to turn when the screw is tightened. Not much tension is needed, so don’t over-tigthten the adjusting screws.
