The interior of your piano should be out of bounds to you and your family. Any dealings with your piano's interior should be handled by a qualified piano technician.

Every 2 to 3 years, depending upon the exposure to dust and dirt to which your Steinway piano is subjected, the interior should be cleaned by a professional. If this step is neglected, you run the risk of exposing the piano's complex workings to undue wear at the hands of abrasive dust and dirt particles. If a pencil, coin, hairpin, or foreign object of any kind should fall into your piano it should be removed at once by a professional piano technician. Foreign objects can seriously affect the action and tone of the piano.
