Tips and Tricks for Repairing Sticky Keys
If you are experiencing sticky keys on your piano, there are several tips and tricks you can try before calling in a professional piano repair technician. Here are some of the most effective techniques for repairing sticky keys:
- Clean the keys - As mentioned earlier, a buildup of dirt and debris on the key surface can cause keys to become sticky. The first step in repairing sticky keys is to clean the key surface. You can use a soft cloth dampened with water or a gentle piano key cleaner to wipe down the keys. Be sure to dry the keys thoroughly after cleaning to prevent any moisture from seeping into the piano's mechanism.
- Adjust the humidity - If changes in humidity and temperature are causing your piano keys to become sticky, you can try adjusting the humidity in the room. Installing a humidifier or dehumidifier can help stabilize the environment and prevent fluctuations that can affect the piano's mechanism.
- Use graphite powder - Graphite powder is a dry lubricant that can help reduce friction between the keys and the piano's mechanism. You can apply a small amount of graphite powder to the key surface and work it into the mechanism by pressing and releasing the keys several times. Be sure to use only a small amount of graphite powder, as too much can clog the mechanism.
- Adjust the key height - Sometimes, sticky keys can be caused by an incorrect key height. If the keys are too high or too low, they can create friction that prevents them from moving freely. You can adjust the key height by removing the key from the piano and adjusting the felt bushings or key slip. Be sure to consult a piano repair manual or professional before attempting this technique.
- Replace the felt pads - If the felt pads that cushion the hammers and dampers are worn down, they can cause the keys to become sticky. In this case, it is necessary to replace the felt pads. This is a more advanced repair technique and should be performed by a professional piano repair technician.
