Depending on the piano, most have finishes on the exterior sealing the wood that can be washed and deodorized to remove the fragrance.
- Most likely the fragrance is embedded in the exposed unfinished wood and material (such as felt pads) located on the interior of the piano.
- To completely seal these areas will require disassembly of the piano, application of a low-VOC finish and reassembly and tuning.
- This approach may be costly.
I recommend you contact your insurance company for names and recommendations of "insurance reconstruction companies."
Why? Most of these companies have the capability to deodorize furniture, even pianos, from odors such as smoke, and may have the ability to deodorize your inherited piano of the embedded fragrances.
