[CAUT] Mold spore damage

Once?corrosion starts, it can't be reversed. When mold attacks fibrous materials, like felts, it cannot be reversed. Bottom line: In addition to a new finish, new felts,?strings and pins.

To the list,?
?
I recently examined a Steinway L - nice instrument, recently restrung and refinished - that spent a couple days in premises that were flooded. There is no direct water damage to the piano - but it did spend some time in a very humid environment, standing on water-saturated floors in fairly warm weather before the owners were able to move it out of there to a storage facility. The most obvious damage is to the finish - it pretty much cracked apart (looks like semi-gloss water-based nitrocellusose) in long, parallel cracks. Other problems include some surface corrosion on the strings, and totally gummed up action centers.?
?
They had flood damage technicians test air samples from the premises, and they found a high mold spore count (a particular mold specific to water damage). This requires that the premises and all contents be "hepa-vacuumed". Eventually I am going to see their report and perhaps even consult with them - but in the meantime, does anyone know anything about "hepa-Vacuuming", how it's done and what horrible things it might do to the poor piano (or not)??
?
Thank you,?
