What you need
- Enzyme cleaner
- Breaks down the proteins and acids in vomit that cause lingering smell.
- Plastic scraper or card
- Lifts solids without pushing them into fabric.
- Wet-dry vacuum
- Pulls liquid out of seat foam and carpet padding.
The first hour
Cleaning to the foam
Vomit is acidic and protein-rich, and it soaks into seat fabric and foam quickly. Surface cleaning leaves residue in the foam that sours over the next few days. After removing solids, apply an enzyme cleaner generously enough to reach as deep as the spill went, let it work for the time on the label, then extract with a wet-dry vacuum. Repeat if needed, then dry with doors open and a fan.
Check under the seat and in seat tracks, where liquid often runs. Seat belts may need cleaning too; wipe them rather than soaking.
Preventing a repeat
For kids or adults prone to car sickness, keep a bag and towels within reach, crack a window, keep the car cool and avoid strong air fresheners, which can make nausea worse. A washable seat cover or protector under a car seat makes cleanup much easier if it happens again. Stopping for fresh air on long drives also helps. Seat belts and buckles near the spill should be wiped with a damp cloth and mild soap, since soaking belts can weaken them. A short drive with windows open afterward helps clear lingering smells. If the smell persists after two rounds of cleaning, the foam may need professional extraction or the cushion may need replacement.
Full cleanup after the first hour
Apply enzyme cleaner
Generously, to the depth the vomit reached.
Let it work
Follow the label's contact time.
Extract
Pull liquid and residue out with a wet-dry vacuum.
Dry and recheck
Dry fully, then smell after the car sits closed.
Common questions
Why does the smell come back after cleaning?
Residue left in the foam or padding. Another enzyme treatment and thorough extraction usually solve it.
Is baking soda enough for vomit?
It can absorb some liquid and odor, but an enzyme cleaner is needed to break down what soaked into the foam.
