Few things ruin a drive faster than an unpleasant odor lingering in your car. Whether it's leftover fast food, damp carpets, or something more stubborn like smoke or vomit, bad smells affect comfort and make passengers less eager to ride along. The good news is that with the right steps — and a little consistency — you can get rid of car smells and keep your interior fresh.
At AutoManiacs, we believe car care shouldn't feel overwhelming. With simple, accessible products and clear guidance, removing odors becomes less of a chore and more of a quick routine that restores pride in your vehicle.
Common Causes of Car Odors
Before diving into solutions, it helps to know what's behind the smell.
- Everyday culprits: food wrappers, coffee spills, pet hair, and sweaty gym gear.
- Environmental factors: water leaks leading to damp carpets, mildew in air vents, or a musty smell from the AC system.
- Accidents and spills: vomit, milk, or even fish can leave stubborn residues.
- Smoking: tobacco smoke is notorious for clinging to fabrics and ventilation.
A recent Consumer Reports article confirms that many odors come from hidden sources, such as spills beneath carpets or moisture in HVAC systems, making thorough cleaning essential.

Step-by-Step Guide: How to Remove Smell from Cars
Step 1 — Identify and Remove the Source
Start by locating the culprit. Check under seats, mats, and in the trunk. Old food or damp gym clothes are easy fixes once removed. For sticky messes or stains, AutoManiacs Interior Cleaner makes quick work of multi-surface grime, from plastics to fabric seats.

Step 2 — Deep Clean Fabrics and Surfaces
Vacuum upholstery, carpets, and mats thoroughly to remove dirt and debris. Sprinkle baking soda on carpets to absorb car smells overnight, then vacuum again. To protect and refresh surfaces, apply AutoManiacs Interior Coating — it restores the finish, adds UV protection, and helps prevent odors from setting in.
Step 3 — Air Out and Freshen Up
Open all doors and windows when the weather permits. Run the fan with the AC off to circulate fresh air through vents. Don't forget the cabin air filter — replacing it can instantly cut down odors trapped in the HVAC system.
How to Remove Specific Car Odors
How to Remove Musty Smell from Cars
A musty smell often points to trapped moisture. Check for damp floor mats, leaky door seals, or clogged sunroof drains.
- Dry out the area with towels or a wet/dry vacuum.
- Sprinkle baking soda on carpets and let sit overnight.
- Clean vents by running the fan with the AC on high.
Prevent future issues by coating surfaces with AutoManiacs Interior Coating, which protects against moisture buildup and other environmental factors.
How to Remove Vomit Odor from a Car
Vomit odors are among the toughest due to the presence of acids and bacteria. The key is fast action:
- Remove solids carefully and blot with paper towels.
- Mix a mild solution of baking soda and water (or vinegar) to neutralize the smell.
- Finish with AutoManiacs Interior Cleaner to sanitize and restore freshness.
If the odor lingers in the carpets, sprinkle more baking soda and vacuum the area the next day.
How to Remove Pet Odors from a Car
Dogs and cats bring joy — but also dander, fur, and occasional accidents.
- Vacuum regularly with a brush attachment to pull hair from fabric.
- Use baking soda to reduce lingering smells.
- For quick refreshes after pet rides, a few sprays of an interior cleaner keep surfaces clean and smelling neutral.
How to Remove Cigarette Smoke Smell from a Car
Smoke seeps into fabrics, plastics, and the HVAC system. While a quick wipe can help, eliminating it fully requires a deeper process: cleaning upholstery, replacing the cabin filter, and possibly using ozone treatments.
