Pianos that are used for performance or for recording will need to be tuned more often. Temperature Pianos are damaged by extreme heat as well as extreme cold. Ideally, a piano will be maintained in a room in which the relative humidity remains constant year-round. Room humidifiers should be used whenever possible in those parts of the world in which there are cold, dry winters. Dehumidifiers are essential in tropical climates.
Air conditioners can also be helpful especially if they run fairly constantly.
Piano Interior Keep fluids away from the piano. Juice, soda, even water spilled into a piano can do severe damage. Never touch the bass strings. Residue from hands and fingers causes corrosion, which can cause the bass strings to buzz and to lose clarity and power. Remove dust with a leaf blower or with the exhaust from a vacuum cleaner.
