How to Make Your Car Smell Good (and Keep It That Way)

You've done it before. A hanging tree from the servo, clipped to the mirror, and three days later the car smells like a scent mixed with a musky interior. So you buy another one.

The freshener was never the problem. The order was. A freshener is the last step in making a car smell good, not the first, and skipping what comes before it means paying for something that's fighting a losing battle.

The four steps

Step 1: Find the source

Two minutes of looking saves you buying fresheners that can't fix the real problem. Check:

• Under the floor mats. Damp mats that never dried properly are one of the most common causes.
• Under both front seats. Wrappers, fries and forgotten fruit end up here.
• The boot. Gym bags, sports gear, groceries and work gear left too long.
• The air conditioning. If it smells musty mainly when the fan is running, the cabin air filter or the AC system is the likely culprit, and that's a job for a mechanic or AC specialist.

For the full list of causes and what each smell usually means, see why your car smells bad.

Step 2: Clean it out

This doesn't need to be a full detail. It just needs to happen before the scent goes in.

• Vacuum properly, including under the seats and the gap where the seat base meets the backrest.
• Wipe down hard surfaces, especially cup holders and door handles.
• Dry damp mats fully before putting them back.
• Flush the air. Windows down, fan on high for a few minutes to push stale air out of the cabin and the vents.

Step 3: Reset the cabin

Vacuuming picks up what you can see, but carpets and mats hold onto smells. Our Handover Spray is made for carpet and fabric, and it contains ethanol, which helps tackle odours in the fibres as well as leaving a fresh scent behind.

• Mist the soft surfaces. A light spray over carpets, mats and fabric after your clean, then let it dry.
• Treat it like cologne. Keep it off plastics, leather, Alcantara and suede. If any lands on plastic or rubber trim, wipe it off with a damp cloth.

Step 4: Add a car scent that lasts

• Pick the right format. Paper trees and most vent clips give up their fragrance in days. A gel releases gradually over weeks, so the car keeps smelling good long after the first drive.
• Match the scent to your car. Bigger cabins and anyone who wants presence suit the more distinct scents. Smaller cabins, or anyone sensitive to fragrance, often prefer something more balanced or subtle.
  

• Put it where air moves. Front centre cup holders or near a vent. Our placement guide shows exactly where it works and where it doesn't.
• Use the lid. Lid on for a subtler scent that lasts longer, lid off when you want more presence.

Mistakes that undo all your work

• Adding a freshener before cleaning. You don't get a fresh car. You get both smells at once.
• Mixing different scents. Two different fragrances in one cabin clash rather than combine. In a large SUV or van, two jars of the same scent placed apart is a different thing entirely, and it works well.
• Leaving it on the dash in the sun. Heat speeds up how fast any freshener gives up its scent. A strong first week, then not much.
• Judging it the moment you get in on a hot day. A cabin full of hot, stale air buries fragrance. Crack a window or run the fan for a minute and give it a chance once fresh air is moving.

Common questions

What's the fastest way to make my car smell good?
Clear out any rubbish, open the windows and run the fan on high for a few minutes. That alone makes a big difference. Then add a freshener somewhere with airflow.

Why does my car still smell bad after using an air freshener?
The source is still there. A freshener adds scent, it doesn't remove whatever is causing the smell. Find it and clean it out first.

Where should I put a car air freshener?
Front centre cup holders or near a vent. Avoid deep door pockets, centre console storage, the parcel shelf and the dash under the windscreen.

What's the best car scent?
It depends on your car and how much presence you want. Aqua Fresh, Citrus Lift, Cool Melon and Berry Chill are our most distinct. JDM Fizz, Grape Ice and Very Vanilla are more refined and balanced. Auto Aurora is our subtlest.
