Ozone
After a month of driving with the vents wide open in my new used car, I decided that
I had to do something about the sickly smell of pine scent. (The stink was clearly not going to just, go away on it's own.) OK . . . . So,,, I already had a ozonator operating on my swimming pool. So I disconnected it from the pool and jury rigged a 6-9 volt CPU fan over the air inlet hole and drove it with one of the many power adapters that had kicking around. Connected both the fan and the ozonator. (Appears to simply be a rectangular air tight box with a blue UV?? bulb inside and a half inch air inlet hole on one end and an air outlet hole on either end.) I ran an extension cord out to the car and let the ozonator run for about 20 hours. At noon the next day I opened all the windows and aired the car out really well. When I got in and took her for a test run, I couldn't believe my nose. That sickly sweet heavy pine scent was gone and nothing else was left behind. Just a totally neutral odor,,, NOTHING! The smell of death was gone! Now the metal working related question! If I let this run in the background in my shop to get rid of the smell from rancid oil etc. would it build to unsafe concentrations of ozone. It's a fairly large room (24 x 24) Thanks |

(clip) ^^^^^^^^^^^^^^^^ I don't think so. Ozone is O3, which is unstable. It breaks down into O2 and a free oxygen ion, which combines with the smelly stuff, or with another oxygen ion, to form O2. Ozone has a characteristic odor, which you can sometimes smell around sparking electric motors and such. If you start to notice that odor in your shop, turn off the ozonator and wait a while. |

Probably the same thing would apply to their competition's air ionizing "purifiers". In the last few weeks I've noticed that the Ionic Breeze TV ads are touting the fact that they now have some sort of catalytic converter on them which, If I heard it correctly, turns the ozone back into oxygen. Regarding your "blue bulb": Years ago some home laundry dryers had a UV "germicide bulb" in them which looked like an automotive tail lamp bulb and ran on low voltage. It had a filament in it and I think the glass was a type which would pass UV. I bought one of those bulbs about 20 years ago from an appliance parts shop, mounted it inside a soup can shield with a doorbell transformer and dropping resistor tacked on and used it to clear those old UV eraseable EPROM static memory chips. It looked sort of blueish inside when lit, the couple of times I risked one eye and peeked at it at arms length. :-) Thanks for the mammaries, Jeff -- Jeffry Wisnia (W1BSV + Brass Rat '57 EE) "Truth exists; only falsehood has to be invented." |

Don't run it for a long time. Ozone will eat up most plastics. Vinyl will
turn brittle rather quickly. -- Glenn Ashmore I'm building a 45' cutter in strip/composite.

Besides being really reactive with rubber and many plastics it will also react with the living tissue in your lungs. The extra oxygen atom combines real easy with all sorts of stuff and kills cells. This is why your pool has an ozonator. It is a good disinfectant. I wouldn't use it in your car again if you can help it because it will start to damage rubber items. Like door and window seals. It is a good deodorant, as you found out. It is used to deodorize houses after fires, dead refrigerators that leak meat juice, cat and dog pee, etc. But the oxide layer that stops the odors is thin and if disturbed will start to smell again. So the houses are deodorized and then painted to seal. ERS |

Charles, Leo, Lawrence, Glenn and Eric
Thanks Guys The ozonator was worth it's weight in gold for me as this was an 05 model car. At first I thought it was just the stinky evergreen tree hanging on the mirror but after the car was bought and paid for I realized that the odor was never going to come out on it's own. The thing is that it works amazingly well and I just wanted to relay that to the group. Now , I had done some reading and some places it says the 03 is a very safe disinfectant and other places where it says it is dangerous. In any case I will err on the side of safety. Again thank you all.

Ozone is toxic on long exposure. An oxidizing agent like SO3.
You might want to only use it periodically instead of facing consttant exposure in your shop. As to the car, wouldn't burning a pack of sulfur matches have done the job easier? MadDog |

SO3 is an acid anhydride gas.
It would function in this case as an oxidizing agent just as the ozone does. It's a whole lot easier to get and the 'acid` smell functions as a safety warning so you don't breath it in for too long. I believe the toxicity is higher than the ozone, (the gas goes into solution on the moist surfaces in your lungs, O3 produces hydrogen peroxide, SO3 - sulfuric acid), but the amount in question would be small and the exposure short.

I always watched that silly stunt (being too stupid to shield it so the toxic gases could waft away before lighting the other toxic material which you'd ingest) in horror, too. Yuk! I'm 17 years cig-free. As a pipe smoker (no longer), I couldn't stand the taste or smell. Nor could I. I quickly graduated to a butane lighter. Pine-Sol, the multi-use product. :-) Yum!

I ran an extension cord out to the car and let the ozonator run I had forgotten the experiment for three days and when I opened the door the door panel fell squarely off and shattered on the driveway. When the fresh air hit the interior it crystallized with pretty fuss and all fell to the floor. While vacuuming the fluff out between the springs of where the passenger seat was the vacuum stuck to a cardboard cut out of a tree. LOL, 'Honey, look I told you I'd find the source of that smell.' Now the metal working related question! How can I keep all the exposed metal from rusting? Reminds me again of how I ruined the step mother's car by washing it with 50% ZEP. Dad said to clean it very good, he didn't say I couldn't take it down to the molecular level. ooops Really shouldn't hurt it too much, spas survive it. I just hate 03 smell and would have been worried it would somehow sick in the car. I'd rather die from long term chlorine smell than ozone smell. |
