Cleaning Mouse feces and urine out of an old garage kept guitar

[Phil Goodson]

So just what exactly does the ozone do chemically to remove the smell?

Oxidizes urea to Nitrogen, Carbon dioxide, and water. Maybe other things.

[CarlM]

The ketones, aldehydes and organic acids, along with urea, coming from the outgassing are generally more reactive than components of wood odor. The EPA website I list below says the following as a summary of a longer section on whether the generators are effective:

Are Ozone Generators Effective in Controlling Indoor Air Pollution?
Available scientific evidence shows that at concentrations that do not exceed public health standards, ozone has little potential to remove indoor air contaminants.
Some manufacturers or vendors suggest that ozone will render almost every chemical contaminant harmless by producing a chemical reaction whose only by-products are carbon dioxide, oxygen and water. This is misleading. .....

That reflects what we discovered when doing controlled experiments.
