Ozone oil reactions

Ozone is an extremely powerful oxidant, so powerful, in fact, that what you intend to use it for will probably result in a fire or even explosion, particularly if the metal catalyzes the oxidation of the oil or grease you're trying to remove. It is also fairly toxic. Furthermore, it would probably be in violation of certain environmental protection regulations, so you'll probably want to check with your local authorities on this. Using alcohol or oter solvents will probably be a lot safer than using ozone.

Why ozone? It's a bit hazardous to handle, as other posts have indicated. Wouldn't a simple liquid detergent be a better choice?

Or a flame thrower!

Oxidizers must be avoided at all costs to clean oily surfaces.They will only compound the problems. Apart from the fire hazard, oxidizers thicken the oils and will make them even more stubborn. Bitumen is a good example. The more oxygen you add, the tougher it gets. Best solution to remove the toughened greases is to use Solpar, 3 % solution. Just spray on the surface, wait for an hour and then wash with warm water. The grease will be gone and the oils spilt into molecules and the water run off is then biodegradable.

Steve,

How did you arrive at the mistaken conclusion that ozone will freshen the air?

Here is a link to an EPA site discussing ozone.

I have been under the impression for about 60 years that the odor I associate with model electric trains is ozone caused by the sparking of the brushes on the cheap electric motors and the wheels as they make and break contact with the rails. I was also under the impression that in the small quantities generated by the trains, the ozone was exhilarating, while knowing that in large quantities it was toxic. I have never attempted to confirm this impression, though I'm sure I have stated it as fact. Anybody know for sure?

A statement such as "in small quantities it is exhilarating, while large quantities it is toxic" could also apply to a plethora of toxins (including narcotics). This observation seems to support your hypothesis. However it is possible that something other than the ozone from the model electric trains is responsible for your feeling of exhilaration.

Caution!! Ozone levels high enough to do what you mention would

be highly toxic to humans, and would not be too effective at it without

heating which poses a fire hazard.

The application I am concerned about is in commercial kitchen ventilation. A company is selling UV lights installed in the kitchen exhaust grease hood with the claim that the ozone produced will oxidize the grease resulting in cleaner hoods. I doubt that this works. First not very much Ozone will be produced, the temperature is about 125 F, and the air stream is moving at about 1500 fpm. The elevated temperatures would probably decrease the life of the unstable Ozone and the velocity of the air stream would result in short residence times not long enough for a reaction to occur. Interesting comments from all.

Thanks
