Defending Your Piano from the Perils of Too Much Moisture

You’ve invested a lot of time, energy and love into your piano.

Perhaps you diligently practice two or three hours a day. Perhaps you record or compose gorgeous music. In any event, you want to extract the maximum usefulness from the piano and protect it against damage and abuse.

One of the most insidious threats to pianos is excess moisture and humidity.

Consider how much effort you spend on protecting the piano against “brute force” hazards: how many times have you warned your five-year old “no playing in the piano room” out of fear that he will smash the keys with a toy or worse? Unfortunately, most owners do not spend enough time guarding against subtle but potentially lethal (for the piano, that is) threats like moisture.

Here are some tips:

  • When it rains, or when it’s excessively humid, close the windows of the piano room.
  • If the piano gets damp or spilled on, wipe the area clean and dry as quickly as possible.
  • To protect the keys, close the top board when you finish practicing, recording or playing.
  • Make use of the cloth cover to absorb moisture.
  • Take extra precautions if your piano is especially “moisture vulnerable” – that is, if you live in a humid region, if you live by the coast, if you don’t have a good ventilation in your room, if the piano is in a concrete building, if there is poor drainage in your area, or if your piano room has a history of leaky roofs.
  • Vigilance is also key. If you notice that piano smells strange (e.g. like mildew or rotting material), or if something “just seems off” about the quality of the tonality, act sooner than later to identify the problem and solve it.

If you catch water or moisture damage early enough, you may be able to protect, repair or salvage the instrument at a relatively minimal cost. If you wait for the problem to get “so bad that you just can’t take it anymore,” you might have to pay a pretty penny to restore the instrument, or you may even have to buy an entirely new piano.
