The outer surfaces of all casework and other parts can be cleaned in the same way you would clean furnishings. Where the finish is stable and in good condition, dusting followed by an occasional wax polishing (approximately twice per year) is appropriate. Light damp cleaning with a slightly moist clean cloth is also effective if the finish is modern and in good condition. The keyboard facings of most pianos and other instruments are either ivory or a synthetic substitute. Bone was sometimes used on earlier instruments. Ivory keys can be cleaned with a soft cloth or swab slightly dampened with water to which has been added a few drops of detergent. The keys should not become too wet because ivory occasionally reacts to water. The same treatment can be used for synthetic keys. More care should be taken with bone key facings because bone is more reactive to moisture. It is not advisable to try bleaching piano keys. Although a bleach may be effective in making them whiter, the effect is only temporary, and bleaches can damage ivory.
