Even with a well-maintained grand piano, dust is deposited on the soundboard below the strings. Cleaning the soundboard is difficult - and quickly causes scratches in the sensitive varnish of the soundboard. We offer a special soundboard cleaner set (3 pieces) from specialist dealers. Three flexible metal rods (brass) - a handle on top, covered with red cashmere at the bottom - with which the different areas can be reached through the stringing. A spare strip of cashmere is included in the set. This allows almost every place on the soundboard to be reached gently and the dust to be caught. Loose dust can then be easily removed with a vacuum cleaner. We have been using these sets for a long time and are very satisfied with handling and durability.
