I recently purchased a studio that was built in the 90s. It has quite a few rooms and a large commerical space at the front that was used as a cafe. There is a lingering odour of kinda patchouli / stale I can't seem to get out. I picked up an ozone machine (pic attached below) and was thinking about running it in several rooms ... the control room and tracking room etc. Anyone have any experience with machines like this? I've done some research and know there's to be no People, Pets or Plants around while running it and you need to allow ample time to air out etc. But I am wondering if there is a risk of damage to microphones, outboard gear, amps etc? Any input would be super appreciated, or alternative ways to get smells out that will not effect gear / patch lines etc thanks!

Can't hurt!! Bleach helps. You can get the lemon scented kind and put in a spray bottle, diluted with water, and spray it around. I mean, sure it's an investment (local dollar store: $2 for the bottle, a dollar for the bottle of bleach) but it works.
And if you have any insect or rodent problems or smells, nothing beats Irish Spring

Ozone, or O3 (as opposed to atmospheric oxygen O2) is harmful to humans. At ground level it's a component of smog, and in machine rooms and around large electric motors it's considered a workplace hazard over 0.1ppm in 8 hours and these generators can fill rooms to 10x the hazardous dose within hours. There is also almost zero real scientific studies that show that ozone is effective at binding odor chemicals.
The best option is to find where the odor is coming from and clean it. Bleach is generally effective for biologic sources as noted earlier in the thread. If it's an electrical or chemical source, you might have to remove them.
I have used one for a couple different applications and it made an obvious difference. I wouldn't even consider it debatable, given these items carry none of the original smell months later. I only used ozone after just about every reasonable chemical and enzyme treatment failed. I think there may be some confusion regarding scientific evidence as the EPA states that ozone levels safe for breathing are not effective at odor removal. The commercial unit you have is absolutely not a breathing-level treatment. The "household air cleanser" types are the ones that are often called scams.
I feel treatment is safe unless you are ignoring the basic precautions for some reason. Get all living things and sensitive objects out of the room, seal any air pathways out of the room, and let it air out for several hours when finished, before allowing any living thing back in.
"Sensitive objects" is a subject you'll have to research. Ozone machines are popular in auto resale because of their effectiveness in getting smells out of cars. Some people have reported leather damage, but that seems to be related to over-dosing (too powerful a machine for too long). Again, look into it. I don't think you'll have a problem in a studio if you use an appropriate machine for the recommended length of time. I used one to get smoke smells out of guitars and it was very effective, and after one year I haven't seen any damage to the instrument or recurring smells. Treated my wife's boots to get animal urine smell out. First treatment was about 90% effective. Second eliminated it. It's been several months and the leather shows no signs of degrading.

Just to report an update, used the Ozone machine in the commercial space at the front and the live tracking room and it worked like a freakin charm. Reduced the smell by 90% ... Kept it away from mics and outboard so the control stayed locked up... It really worked well, let it air out for a day before re-entering. thanks for all the helpful advice in this thread!
