How to Get Rid of Car Smells
From damp dog to stale smoke, find out how to eliminate stubborn odours for good using UK-proven methods.
Why does my car smell?
Unpleasant odours in a car are rarely just a nuisance; they are often a sign of bacteria, mould, or trapped particulates. In the UK's damp climate, moisture is the most common culprit, leading to a "musty" smell that usually originates from the air conditioning system or damp floor mats.
Identifying the source is the first step. If you're buying a used car, a lingering smell can even be a sign of a previous write-offwhere flood damage wasn't fully remediated.
DIY Odour Removal Methods
For minor smells, you don't need to spend a fortune. Most solutions are likely already in your kitchen cupboard.
- Baking Soda: Sprinkle liberally on carpets and seats, leave overnight, and vacuum. It neutralises acids that cause odours.
- White Vinegar: Place a bowl of vinegar in the footwell overnight. It absorbs smells without leaving a permanent vinegar scent.
- Coffee Grounds: Dry grounds are excellent at absorbing strong scents like cigarette smoke.
- Air Con "Bombs": Available at Halfords or Amazon for £7–£12, these sprays circulate through the vents to kill bacteria in the evaporator.

Checklist for a Fresh Car
Change the Cabin Filter
Often overlooked, a dirty pollen filter (located behind the glovebox) is a primary source of musty smells.
Check for Damp
Lift the floor mats. If the carpet is damp, you may have a leaking door seal or blocked sunroof drain.
