Hi jassz,

The detail shop may not have run the ozone long enough. Smoke is a tough contaminant to overcome. It is an organic compound though and it can be oxidized.

Ozone is a very powerful oxidzer. However, it needs time to work and that's a downside.

The ozone smell will fade after a while since it has a half life of 30 minutes or so.

I would use a Biozone 500 model in your car every night for at least a total of 48 hours. Also, I would run it when it's hot out and the windows are up. The pores of fabric/leather open with heat and that's when you get the smell.

I would run the ac system on recirc mode for 30 minutes. It may need more than one treatment.

Then I would place the Biozone right near the air intake for the AC system. Let it run for a half hour and do this several times. No need for the fan to be on high.

The units run on twelve volts with a small ac adapter. They take pennies a day to operate.

Best,
