Oxidation does not happen without a source of Oxygen. Ozone is such a source in that the element "O" is present. things don't rust without the presence of oxygen and they don't deteriorate, due to bacterial action, without oxygen to support the bacteria. Ozone in and of itself, being a 'powerful' "bleaching" and "oxidizing" agent will support more rapid corrosion, rusting, drying out of rubber, break down of vinyl compounds, etc. than will oxygen. Ergo any "corrosive capability" of deposited soot/smoke will be greatly enhanced by the introduction of ozone. For this reason I would not suggest putting a decent piano in an "ozone tent". If memory serves me correctly Dave Swartz has told us on several occasions just exactly why this should not be done............ BTW does anyone know anything about Dave? Is he OK? Jim Bryant (FL)
