<HTML>Marcel;       It's very difficult to 'clean' a piano that has been in fire. The smoke can penetrate the wood and ozone will not solve that problem. The first day of high humidity will re-kindle that awful smell. The smoke may show on the outside but I'll bet the 'stink' is on the inside and ozone will not solve that problem within the wood.      I would not even begin to take that chance. Be safe....total the pianos. Tommy Black Decatur, Ala.</HTML>
