The dulcimer is a delicate and fragile musical instrument that cannot withstand falling, pressure and bumps, so the maintenance of the dulcimer is very important. Tuning before use, and dustproof after use; usually pay attention to keep the piano clean, pay attention to bumps when loading and unloading (transportation), pay attention to sun protection, rainproof, moistureproof, dustproof; you can oil the strings ( Vaseline or white oil), and tune regularly; if you don’t use it for a long time, loosen all the strings and put them in the piano case, pay attention to sun protection, rain protection, and moisture protection.

The strings should not be touched frequently except for playing, so as not to rust and deteriorate due to the sweat on your hands. Due to the long-term use and tuning of the strings, the metal filaments wrapped around the strings will loosen and peel off, which also directly affects the clarity of the piano's pronunciation, and new strings should be replaced. Generally speaking, new bar codes are only semi-finished products and need to be trimmed before they can be used. The code bar of the piano should be placed in a certain position, and a slight movement can change the sound of the piano. The contact part between it and the panel should be tight, so that it can be placed stably and firmly, so that each string can sound evenly. The height of the string code has a great influence on the sound quality of the piano, and its height must be determined by the piano and treated individually.

In order to keep the piano clean, it is necessary to wash your hands before playing, so as to prevent the dirt and sweat on your hands from contaminating the piano, which will cause the paint to peel off. In addition, it is absolutely forbidden to smoke while playing, to avoid fireworks falling on the panel and cover and damaging the paint. If there are stains on the dulcimer paint surface, it should be wiped clean in time. Stubborn stains can be wiped off with a soft fabric dipped in a little toothpaste. The dulcimer has been used for a long time, and if a single area of lacquer peels off, in addition to repairing it with lacquer, you can also use walnut kernels to wipe off the lacquer part, which can also play a protective role.
