Exhaust smell
I work in the insurance restoration and mitigation industry and use ozone where appropriate. The drawback to ozone is that it accelerates the degeneration of rubbers and vinyls. It will affect our good ole LP albums, refrigerator gaskets, dryer gaskets, VHS etc. So, those items affected have to be removed from the area or protected, We usually will put painters tape around the refrigerator door etc. to seal and protect. Once the source of the odor is removed meaning any loose or latent residue it does a very good job at eliminating odor. Failure to remove all of the contaminating material prior to the ozone treatment will result in the odor eventually returning. So, that is key! When using ozone you need to make sure there are no pets in or near the area, people cannot be on board during the treatment. The saloon must be closed up tight. When the treatment is over ( usually only an hour or two depending on the size and strength of the unit) the saloon must be thoroughly aired out before occupancy. We send someone into the home, open the windows and he then gets out as soon as he can. If you stay below during the treatment or before the area is properly aired out you will get dizzy and most likely get a headache due to the lack of O2 and run the risk of passing out. In the I lieu of using ozone, the industry is moving more and more toward what is called a Hydroxyl treatment. It is just as effective, does not harm any of the above listed materials and allows for a more rapid occupation of the area. You do not have to buy one as you can rent one at many rental companies. If a rental company in your area does not have one you can call an insurance restoration/ mitigation company and rent one for a day from them. Hydroxyl's are billed out according to how many "optics" are in the unit, 2 or 3. Two optics bills out on the East coast @ $ 180.00 per day and three optics at $228.00 per day. That includes the labor for the tech to deliver, set up, return and carry away. I do not know the current rental rates but if a rental company near you has one it will be cheaper than a mitigation company rental. Buying one is not feasible as they start at a couple of thousand dollars for the smaller unit and go up from there.
Hope this helps. Happy to help if you have any other questions.
