3 to 5 hours of active work plus an overnight ozone treatment for severe cases. Light odor (faint pet smell, occasional food spillage) clears in a single 3-hour visit. Heavy odor (long-term smoking, soaked-in pet urine, vomit) takes 5+ hours of extraction and an additional overnight ozone session in your garage or driveway.
The sequence: full interior detail with steam extraction (1.5 to 3 hours depending on severity), enzyme application and dwell time (30 to 60 minutes for the neutralizer to break down the molecules), then either same-day completion or set up the ozone generator for an overnight treatment that lets the active oxygen reach every cabin surface and HVAC duct.
We schedule heavy-odor jobs as the first appointment of the day so we can run the ozone treatment overnight without disrupting your driving — you wake up to a car that is ready to ventilate for an hour and then back to daily use.
