The Problem

A downtown Raleigh resident who drove for a rideshare service on weekends had a persistent vomit smell in their Honda Accord. A passenger had gotten sick in the back seat weeks earlier, and despite the driver's immediate cleanup effort with towels and spray cleaner, the odor had soaked into the cloth seat cushion and carpet padding on the passenger side. The smell worsened in the afternoon sun when the car sat in surface lots between shifts, and it was costing the driver their rating — multiple passengers had commented on it. Beyond the primary odor source, the general cabin had absorbed a mix of smells from thousands of rideshare trips — cologne, perfume, fast food, and body odor had layered into the headliner, seat fabric, and carpet over time. The floor mats were worn thin and stained from hundreds of shoes tracking in rain, mud, and parking garage grime. The driver needed a complete odor removal for the car interior to continue working without complaints.

Our Process

• Identification of primary vomit odor source in rear passenger seat cushion and carpet
• Seat cushion removal to access and treat the foam padding underneath
• Bio-enzymatic deep treatment on affected seat foam, fabric, and carpet padding
• Hot water extraction on all cloth seats and full carpet surface area
• Headliner steam treatment to release layered rideshare odors
• Floor mat deep cleaning and extraction
• HVAC system antibacterial fogger treatment to clear duct-carried smells
• Sealed-cabin ozone generator treatment for 3 hours
• Cabin air filter replacement
• Post-treatment ventilation and multi-point odor verification

The Results

The Accord was completely odor-free after the treatment. Removing the seat cushion to treat the foam directly was the critical step — the vomit had soaked through the fabric into the padding where surface cleaning could never reach it. The enzymatic cleaner broke down the organic matter at its source, and the ozone session neutralized the layered rideshare smells that had built up in the headliner and fabric over time. The HVAC flush and new cabin air filter ensured nothing was recirculating through the system. The driver reported that their next weekend of rides went without a single odor complaint, and their rating started recovering. In Raleigh's warm climate, organic spills left untreated in a car become significantly worse within days — the heat accelerates decomposition and drives the smell deeper into materials.
