Has anyone used an ozone generator for odor removal? I want to get rid of what I guess is the odor from the engine. It is not an exhaust smell. I have been told it is from deisel fuel that may have been spilled during routine maintaence.

John - an ozone generator is the MOST effective method to rid yourself of unwanted odors. If the odor is organic in origin (which ones aren't??) the ozone breaks it down into water, carbon monoxide and carbon dioxide (all in harmless amounts).

P.S. I was once the importer for the Elcar ozone generator made in Canada.

Hi John,

FWIW ... my best friend has a Hunter 37.5 ... it had an ozone generator on it, and he blames the generator for ruining ALL of the brass onboard. I don't know why the reaction is worse than just tarnish, but apparently it is.

So, if you have brass on your boat, it might be worth your time to see if this is a common problem with ozone generators ... 'just a thought.

I have also heard that the ozone generator can ruin some things. I guesse it is brass. I wonder what else?
Hey Derek, since you used to import these things, maybe you can help us out. What gets ruined? If we do want one, what kind to get?
Thanks

Frank & Buzz - you are indubitably correct! The solution is to put a clear coat of lacquer on all the brass.
I've been out of this market for 20 years so cannot recommend a particular model - just make sure you get an ozone generator rather than a negative ion one or an electrostatic precipitator.

I have also heard ozone generators are bad for rubber type items including seals etc., however, my intention is to only use it once. I own a business that was once severely damaged by an electrical fire which produced more smoke than fire. After the contactors were finished replacing or painting every surface we were left with a very strong smoke odor. They brought in an ozone generator which was rented from a local tool rental, 24 hrs. later the smell was gone. This was a 10,000 sq. foot building. It was truly amazing.

yes ozone is highly reactive with all organic materials including rubber, lungs, etc. Ozone generators are great, I'm just noting that they must be used judiciously. In fact tropospheric ozone is a pollutant generated by a chemical reaction driven by both natural(vegetation) and auto-exhaust/petroleum precursors and sunlight. Hence anyone living in areas in which ozone pollution is persistent will almost certainly notice the short life of rubber products. I lived in Galveston, TX for several years during my graduate school days many years past and was amazed that rubber seals (surrounding car windows etc.) had life times of only a few years before becoming brittle.
