Hello mbs431,
I work for OdorFree Ozone Machines and can tell you all about them. The Hotel is a good product but it is best used in hotel rooms in between guest stays. What we normally suggest for car detailers is the Suite 700. Since you mention that time is of the essence, the Suite 700 outputs more than double the amount of ozone than that of the Hotel 350 and can take care of car odors much more quickly.
To remove car odor, an OdorFree ozone machine is placed on the seat after the vehicles interior has been cleaned (Note: if the seats and carpet have been recently shampooed, it is best to wait until they are dry before treatment). Run an extension cord through the window and leave it open a few inches. Set the dial on the OdorFree car odor remover for 30 minutes to several hours. The treatment time depends on such things as the size of the vehicle, how long it was smoked in, or how deeply entrenched the odors. The windows and doors are closed, except it will be necessary to leave one window open a few inches during treatment, providing a supply of oxygen that creates more ozone (O3). Car odor removal is easy as the interior is filled with ozone and odors are eliminated.
Note: To thoroughly remove cigarette smoke from car as well as other odors that may have penetrated the air-conditioning system, turn on the vehicle fan and select the “re-circulate” option 15 minutes to one hour before the end of the treatment. Upon returning to the vehicle, open the windows to ventilate the interior. The O3 creates a clean, sanitizing smell that dissipates within an hour.
You don’t need to mask vehicle odors with so-called car odor eliminator air fresheners. The vehicle will smell fresh and be free of pollutants, allergens and odors with the OdorFree treatment for car odor removal.
