I never quite understand the extreme reactions supporter and detractors of ozone put forth on these
forums. Well, usually the detractors are the most extreme with death and doom.
Ozone in itself is present in our
environment. It serves both good and bad functions. Whether is it good or bad depends on where it is and what the concentration is.
Using ozone as a tool with a ozone
generator is very effective at removing odors and for killing molds and fungus but comes with some risks. Be aware of the risks and take precautions. It is pretty much that simple.
By way of comparison, welding is very dangerous. Poisonous gasses, risks of burns, electrocution, and blindness, yet people weld every day.
Muriatic acid is very dangerous. Risks of chemical burns, blindness, lung damage from fumes, chemical attack of metals and so on, yet used for
cleaning concrete, removing rust, chemically PH balancing pools or ponds are appropriate uses for this acid.
I have used ozone for
cleaning my
boats for over 30 years and my DNA is still intact. It is a great tool for eliminating any "boat smell". As others have said, just have it running while you are not on the boat.
