For many of us, living in a clean space is non-negotiable. We wash the dishes, vacuum the floors, and do the laundry, ensuring our day-to-day lives feel tidy, organized, and put together. However, nearly half the country admits their cars are messy and cluttered. And since we all spend about 7 hours a week in our vehicles, taking the time to clean your car should really be more of a priority.
However, if you have kids, that’s easier said than done. Between snack crumbs, spilled drinks, muddy shoes, forgotten sports gear, and the occasional diaper or mystery smell, cars can get messy fast. When you’re rushing between school drop-offs, errands, and activities, keeping the interior spotless often falls to the bottom of the to-do list.
The good news? With a few simple habits and the right cleaning supplies, it’s completely possible to keep your car looking tidy and smelling fresh, even with kids along for the ride. Below, we’re sharing practical tips to help you keep your car clean and fresh:
How to Keep Car Interior Clean and Smelling Good
If you’re like many, you’d like to keep your vehicle neat and odor-free. Of course, the right cleaning techniques and products are essential. However, you also need the right prevention strategy and to stop bad odors specifically, you need to know what’s causing them.
Here are some things that can make your car smell:
What Causes a Bad Smell in a Car?
- Food spills and crumbs: Snacks, spilled drinks, and crumbs trapped in the seats or carpet can start to smell as they break down and grow bacteria.
- Soiled car seats: Milk, spit-up, potty accidents, or diaper leaks can soak into car seat padding and straps, creating stubborn odors if not cleaned properly.
- Moisture and mold: Wet shoes, damp floor mats, or water leaks can lead to mildew and mold, which produce a strong musty smell.
- Trash left in the car: Forgotten snack wrappers, cups, or fast-food bags can quickly create lingering odors.
- Dirty cabin air filter: A clogged cabin air filter can trap dust, debris, and smells, circulating stale air throughout the car.
- Pet odors: Pet hair, accidents, or wet dog smell can linger in upholstery and carpet.
- Bacteria in the AC system: Moisture buildup in the air conditioning system can cause bacteria growth, leading to a sour or musty smell when the air runs.
How to Keep Interior of Car Clean and Smelling Good
Clean up spills right away.
If you want to keep your car neat, stain-free, and smelling good, commit to cleaning up spills right away. Whether it’s milk, juice, or your iced coffee, clean your upholstery, seats, and hard surfaces with an appropriate cleaner as soon as you get back home. This ensures the mess doesn’t have time to set in and stew in the hot, stagnant air.
Regularly (and safely) clean car seats.
Car seats are one of the messiest parts of your vehicle. To some degree, we just have to accept that—but there are safe ways to clean car seats. However, carefully read the manufacturer's instructions before using each product. You want to ensure you're using approved cleaning methods and products.
Some car seats have removable padding or covers that you can machine wash or dry, which makes cleanup a breeze. However, many car seats need to be cleaned using only a mild soap (like Dawn or castile soap) and warm water. For step-by-step guidance, read our post on how to clean a child’s car seat safely.
Cleaning your car seats regularly helps prevent odors, keeps your car looking neat, and stops your child from snacking on three-week-old Cheerios. The leftovers probably won’t hurt them, but we can all agree it’s better if they’re not there.
Vacuum the interior when needed.
Crumbs on a vehicle’s floor may not seem like a big deal, but they can actually attract rodents and insects. Because of that, it’s really important to vacuum regularly. We know it’s a hassle to lug your vacuum and an extension cord out to the car, but it’s worth it. And if you want to make it easier on yourself, consider purchasing a handheld car vacuum. It’s a smart investment, especially if you have kids!
Remove trash after every trip.
Trash is one of the biggest contributors to bad odors and general clutter in a car. Empty snack wrappers, drink bottles, and fast-food bags can pile up quickly. To prevent this buildup, try creating a simple habit of having everyone remove their fresh from the vehicle before getting out.
If you do it every time, it quickly becomes a routine that keeps messes from ever accumulating. You can also keep a small car trash can in the backseat to make cleanup even easier during longer drives.
Air out the car when the weather allows it.
Cars are sealed environments, which means there’s very little air circulation. Odors can linger inside with nowhere to go, often clinging to upholstery, carpets, and other soft surfaces. On top of that, moisture from humidity, rain, or snow can create a damp environment that’s the perfect breeding ground for mold, mildew, and odor-causing bacteria.
The solution? Let your car air out. When the weather allows, open the windows to let fresh air replace stale, odor-filled air and help reduce excess moisture. As a bonus, sunlight can help dry fabrics and even kill bacteria and microbes on various surfaces. It’s not a complete disinfecting solution, but it can help reduce odor-causing bacteria and keep your car smelling fresh.
Use washable floor mats.
Floor mats collect the most dust, dirt, and grime in your vehicle. Because of that, they’re often one of the biggest contributors to a car looking messy or smelling bad. Washable floor mats can make a big difference.
Whether you can toss them in the washing machine or simply spray them down with the hose, having a quick and easy way to clean your mats makes regular maintenance much more manageable. This way, you don’t have to scrub the carpet inside your car with soap, water, and elbow grease. Instead, you can just remove the mats, wash them off, and put them back once they’re dry.
Clean vents and replace the cabin air filter.
Your car’s ventilation system can easily trap dust, pollen, and other debris over time. When that buildup collects in the air filter, it can circulate stale or musty smells throughout the vehicle whenever you turn on the air or heat. To prevent this, keep the vents clean and change your cabin air filter according to your vehicle manufacturer’s recommendations. (Filters often need to be replaced about once a year.)
Do quick weekly wipe-downs.
At least once a week, wipe down surfaces like your dashboard, the center console, door panels, and steering wheel. Dust, oils, fingerprints, and sticky residue easily cling to hard plastic, making your car look and feel dirty. A simple swipe with a microfiber cloth and car interior cleaner goes a long way. Usually, the cleaner comes mildly scented, leaving your car smelling as clean as it looks.
Use a mild odor absorber if necessary.
Unwanted odors are a common complaint among car owners. A vehicle provides the perfect environment for musty odors and sour smells to develop and linger. Sometimes a simple car-scent air freshener can get the job done. But often, that vanilla or “new car” scent just masks the existing odor rather than actually removing it.
To truly freshen up your car, start with odor eliminators before adding fragrances. Here are some of the best products and tools for absorbing odors in your car:
Limit the foods and drinks you allow.
Your family should avoid eating or drinking in the car for a few reasons. For kids, choking hazards and projectile risks from hard-plastic or stainless steel cups are the biggest concerns. But beyond those safety issues, eating and drinking in the vehicle can quickly create a mess. Sticky spills, cookie crumbs, and crushed snack pieces can get ground into seats and carpets, leaving lingering stains and odors.
That said, we have kids too. We know that sometimes eating in the car is unavoidable. When it does happen, be intentional about the snacks you allow and avoid choking hazards or foods that are difficult to clean up. We recommend a water-only rule for drinks and sticking to relatively mess-free snacks when possible. Think options like dry cereals, pretzels, puffs, string cheese, etc.
Here’s more on whether car snacks are safe for kids.
Keep a cleaning kit in the car.
One of the easiest ways to keep your car clean is to keep basic supplies within reach. Store a small kit in your trunk or center console with essentials like a microfiber cloth, disinfecting wipes, paper towels, a small trash bag, and a gentle interior cleaner. When spills, crumbs, or sticky spots appear, you’ll be able to clean them up quickly before they turn into stains or odors.
Consider professional car detailing.
If your car has gotten out of hand, consider getting a professional deep clean. A full-service detailing appointment can completely reset your vehicle by thoroughly cleaning carpets, upholstery, vents, and hard surfaces. Instead of feeling overwhelmed by the mess that’s already there, you can start fresh and maintain the space with better tidying and cleaning habits going forward. Make sure to remove your car seats and leave them at home before doing this! Car seats can not be detailed like a car!
What to Use to Clean Car Interior
Vehicle Seats
- Upholstery Cleaner: Use a microfiber cloth or cleaning brush to scrub the cleaner into vinyl or cloth seats (not leather).
- Leather Cleaner/Conditioner: For leather upholstery, apply the leather cleaner or conditioner with an applicator pad.
Car Seat
- Mild Soap: For car seat padding and fabric that aren’t washable, use a mild soap like Dawn dish soap or Dr. Bronner’s Unscented Castile soap. Apply it with warm water and a microfiber cloth.
- Mild Laundry Detergent: If the padding or covers are washable (always check the manual first), wash them as directed using a mild detergent. Avoid anything labeled “heavy-duty” or products containing strong fragrances, bleach, or optical brighteners. Line-dry or machine-dry only if the manufacturer allows it.
- Approved Car Seat Cleaner: Some car seat brands, like Clek, offer cleaning kits specifically designed for safe use with their products. If you have any of these brands, you can use their designated cleaner.
Carpet and Floor Mats
- Carpet or Upholstery Cleaner: A specialty carpet or upholstery cleaner with a microfiber cloth or cleaning brush is the best way to get soft surfaces like carpets and fabric floor mats clean.
- Vacuum: Use a standard vacuum or utility vacuum to clean your vehicle’s floors.
- Compact Car Vacuum: For daily spills and messes, use a handheld car vacuum that lives in your vehicle.
- Mild Soap: If you have rubber floor mats instead of fabric, scrub them with a brush and mild soap and spray them off with the hose. (Outside the vehicle.)
Here’s more on how to clean car carpet.
Dashboard, Console, Cup Holders, and Other Hard Surfaces
- Interior Surface Cleaner: A microfiber cloth and interior surface cleaner can clean hard-plastic parts of the car. This includes the dashboard, steering wheel, gear shifter, console, weather controls, armrests, and more.
- Interior Surface Wipes: Disposable cleaning wipes are also available to clean these surfaces.
Air Vents and Crevices
- Soft Detailing Brush: Use a small detailing brush to gently loosen dust from air vents, seams, and other tight spaces where debris tends to collect.
- Compressed Air: Compressed air can help blow dust, dirt, crumbs, and debris out of narrow vents and crevices. This is excellent for areas that are difficult to reach with a cloth or brush.
- Car Cleaning Gel: Press car cleaning gel into small crevices, seams, and vent openings to pick up dust and debris.
Windows and Mirrors
- Streak-Free Glass Cleaner: Apply glass cleaner in small circles using paper towels, newspapers, or a specialty glass-cleaning microfiber towel.
Seat Belts and Buckles
- Compressed Air or Detailing Brush: Use compressed air or a small detailing brush to remove crumbs and debris from around the buckle and latch areas where dirt often collects.
- Mild Soap and Water: Pull the seat belt all the way out and wipe it down with a cloth dampened with mild soap and warm water. This helps remove dirt, oils, and sticky residue that can build up over time. Allow the belt to fully dry before letting it retract.
Organization
- Trunk Organizer: A fabric trunk organizer keeps vehicle essentials and emergency kits accessible. It also prevents those items from becoming dangerous projectiles.
- Soft-Sided Caddies: Soft totes in the backseat are best for items you use more often. This includes diaper-changing and potty-training supplies, car-seat-safe toys, and cleaning supplies.
- Zipper Pouches: For smaller vehicle necessities like insurance/registration documents, pen and paper, chargers, pressure gauge, etc., store them in reusable zipper pouches.
