The 10 Best Car Odor Eliminators

Ozium Air Sanitizer clears a stale cabin in seconds: one or two short bursts into the cabin, aimed at the air rather than the seats. The glycol mist goes after the airborne bacteria behind many smells instead of laying perfume over them, though the maker says the effect is temporary. This pack holds two cans, and both work at home. Don't leave a can in a hot parked car, and it can't reach a smell soaked into carpet.

When a smell has spread through the whole cabin and the vents, Meguiar's Whole Car Air Re-Fresher treats it all at once. Set the air on high and on recirculate, lock the button, shut the doors and let the mist circulate for about 15 minutes, then air the car out. It leaves a strong scent, Fiji Sunset in this can. Each can is good for one treatment, and the spray is flammable, so nobody stays inside while it runs.

Vomit, old smoke and rotting food call for more than a scent, and Gliptone Odor Goblin releases chlorine dioxide gas that breaks odors down where they sit. Gliptone calls it a deodorizer for after the mess is cleaned up, not an air freshener. The car stays sealed for at least four hours, or overnight for heavy smells. Nobody can be inside, the gas irritates the lungs, and a chlorine smell lingers for a while.

Smokers, and anyone who just bought a smoker's car, are who Armor All Smoke X is made for. Each small can sets off like any car bomb, with the air on recirculate, and sends a fine fog through the vents and over the seats. This pack holds two, so a stubborn smell gets a second round a few days later. The Midnight Air scent is bold and woody, and smoke soaked into the headliner can creep back.

If perfume gives you a headache, Moso Natural Air Purifying Bag works without one. It's a cloth bag of bamboo charcoal that soaks up smells and some dampness, and it leaves no scent of its own. Tuck it under a seat or hang it from a hook. Once a month, set it in the sun for about an hour to refresh it, and the maker says it keeps going for two years. It's slow and can't rescue a reeking car.

Owners of SUVs, vans and crew-cab pickups get more fog for the space from Chemical Guys Total Reset, a larger can sized for big cabins. Set it in the center, run the air on recirculate, lock the nozzle and step out, then air the car out for about 15 minutes before driving. It leaves a light new-car scent rather than heavy perfume. It's a newer line with a short track record, and the can is flammable.

Musty, mildewy air from a damp carpet or a car that sat closed for months suits Star brite NosGUARD. A sealed pouch slowly gives off a deodorizing vapor over four to six hours while the car stays shut, with no spraying. One pouch handles a car or small truck. Dry wet carpet first, or the mildew returns. The vapor is an irritant, so stay out until the car has aired out, and keep the pouch from children and pets.

Smells live in carpet fibers and seat foam, and Chemical Guys Ghosted goes after them there: mist it under the seats, into the carpet and mats, along the headliner and into the vents. A light citrus scent shows where you've sprayed, then fades. Chemical Guys is blunt that it only lasts if you clean the interior first, since on a dirty car the result fades in days. Working through a whole cabin with a trigger spray takes a while.

FunkAway Odor Eliminating Beads is a jar of gel beads that pulls smells from gym bags, pets and fast food while it sits in a cup holder. Peel off the seals, put the lid back on and leave it; the maker says a jar lasts up to about three months. It costs little and needs no setup. Loose beads can look like candy to small children and pets, and an open jar can spill on a sharp turn.

For slow, steady control rather than a quick fix, Ozium Odor Eliminating Gel sits in a vented tub and keeps working on smoke and other lingering smells. It suits a trunk, a work van or the garage where the car is parked. Twist the lid open and leave it; there's nothing to spray and nothing to set off. It works slowly, though, and won't clear a strong smell on its own.
