Maintenance of classical guitar

Guitar maintenance knowledge.
First, the guitar strings should be replaced one by one. The most taboo is to use scissors to cut all the strings when they are no longer relaxed. At this time, the guitar is injured because of the instantaneous unbalanced tension. When changing the strings, we should pay attention to the protective panel, especially the rear part of the bridge, which is vulnerable to scratches at the end of the strings. Attention should be paid to tie the strings so that the tight strings do not suddenly loosen and hit the panel, which often causes serious trauma. The tail of the string is burned with fire, which can effectively prevent the strings from slipping out. (low temperature in winter should be paid special attention to. Brittleness of wood and lacquer surface is brittle. Be careful when changing strings.
2. Climate problem high-grade guitar is made of wood, which is very easy to change physically with the change of weather. Generally, the humidity suitable for Guitar maintenance is about 60%. However, it is still necessary to determine the range of humidity provided for Guitar according to the climatic characteristics of the country of origin. A responsible guitar maker tends to take this into account and do some necessary work on wood before making it. Friends in wet areas should pay attention to the damp proof of guitars. It should be emphasized that an accurate hygrometer is provided for the guitar. There are a lot of hygrometers on the market, but few can accurately reflect the humidity level. I have bought numerous hygrometers myself. The humidity display between them can be more than 30% different. If we maintain the guitar according to the figures provided by such hygrometers, there will undoubtedly be serious consequences. Therefore, if a conditional friend can take the hygrometer to the local measurement unit for measurement.
3. Notice about using French Polish guitar French Polish is very weak, so special attention should be paid to the maintenance, playing attention to clothing buttons, zippers, pens and other hard things. It is strictly forbidden to nail the panel directly. If the music needs to be used, it is suggested to stick a protective film. You can buy protective films for protecting palmtop to protect panels. No nails on the left thumb. Otherwise, after a period of time, you will find that the neck of the guitar has been pitted on your nails, seriously affecting the hand feel. For the friends who try the piano, I suggest that the ugly saying is first, ask them to cut off their left thumb nails and then try the piano. Don’t try to use any material to polish the guitar. Use a cloth, or add a drop of water (or use a special polishing agent for the guitar). Use soft cloth or cotton cloth. Avoid high temperature. High temperature can soften French paint and make it lose its luster. When you play in summer, be careful not to let the paint and sweat contact.
4. The maintenance of fingerboard is relatively simple. It can be maintained two or three times a year with linseed oil or olive oil or special oil for woodwind instruments. When replacing new strings, the fingerboard should be cleaned by cloth and a drop of water (preferably using the above-mentioned maintenance oil). If the finger plate is not cleaned, the dirt will enter the entanglement of the bass string and speed up the aging of the sound quality. As emphasized earlier, the guitar strings should be replaced one by one, so don’t remove all the strings while cleaning the fingerboard.
