Before the current owner purchased the instrument, it was owned by a "piana playur" who used it as a plant stand and dribbled a generous amount of water on the board causing stains. Because the client had limited funds, we agreed I would repair the old board rather than replace it. Removing the water stains proved quite a challenge. In short, I used the standard 2-part bleach from a hardware store. The first chemical is the bleach and the second is a neutralizer. It is very important to use the appropriate amount of the neutralizer because the bleach can leave an acidic residue that may harm the wood fibers over time if left untreated. At least that is what the instructions say. I am personally not real hip on the idea of applying liquid to a soundboard. My objective when repairing a board is to dry it out as much as possible. Under the circumstances, however, I felt this to be the only viable alternative. Once the bleaching was complete, the board had to be completely re-dryed before any sealer could be applied. I also found a few new minor cracks to repair after the board had completely dried out again. Nevertheless, once a new decal was installed, along with the refinished plate, new felt, and new strings, what remained of the stains was barely noticeable. To this day the piano works and sounds beautiful, and no new cracks have developed. I think a thourough drying job followed by a well-saturated seal-coat is the secrete of success to this type of repair. My preference, of course, providing the client has the budget, would be a soundboard replacement. Sometimes you gotta do what you gotta do.
