1. There are many felt made of animal fur inside the piano, so it will change with the change of temperature and humidity. If the air-conditioned room is too humid, the felt will easily expand with heat and contract with cold, and there will be a problem that individual keys can't get up, that is, the keys will collapse. If the room is wet for a long time, it will definitely be bad for the piano, which will lead to moldy wood and damage to internal parts, resulting in poor tone and feel of the piano.
2. Piano is most afraid of sudden big contrast between temperature difference and humidity. To prevent this from happening, you can buy a thermometer. Generally, the indoor temperature and humidity are controlled between 45 and 60, which is beneficial to piano maintenance. You can also buy some desiccant and put it in the lower door panel of the piano. So there is no problem.
Precautions for piano use:
1, in order to ensure the piano paint film is bright and clean, always wipe the surface with a soft cloth. To remove the stains caused by oil stains and sweat stains, you can dip a soft cloth in alcohol or diluted detergent, wipe it on the piano surface, then wipe it with a dry cloth, then apply piano high-grade brightener on the piano surface, and then wipe it with a soft cloth. Usually, the appearance of the piano can be maintained for a period of time, and it is not easy to get greasy dirt and dust. Avoid wiping with chemicals such as acetone and thinner (banana oil).
2. Don't put unnecessary decorations and sundries on the piano to avoid sundries falling into the piano and causing parts failure. When playing, these sundries may also produce * * * vibration, which will affect the playing. Don't put lighted matchsticks, cigarette butts and hot water cups on the piano to avoid scalding the paint. Of course, you can't put the liquid container directly on the piano. Once the container is overturned, the liquid will flow into the piano, and the internal parts will swell and rust, which will bring unnecessary losses to the piano.
3. When playing, you can't hit the keys with your hands or step on the pedal with your feet, so as not to cause mechanical damage to the strings and fracture of the pedal spring. Don't use sharp instruments to depict keys and paint film surfaces. Don't use too much force when opening and closing the piano cover. When opening and closing the piano cover, close the bookshelf first to avoid damaging the keys. After the piano is used, all the covers should be closed, and the piano box should be covered to prevent dust from invading.
