Kill the Funk: How to Get Rid of Car Smells for Good

If you've got an organic smell (food, pets, or 'accidents'), you need an enzyme cleaner. I learned this the hard way when a customer brought in a Prado that had a carton of chocolate milk explode under the passenger seat in mid-January. It was grim. Standard soap won't touch that. Use something like Bowden's Own Pong-GO. It literally eats the bacteria that causes the smell. Spray it, let it dwell, and don't be afraid to get it deep into the carpet fibres.

Honestly, I wouldn't bother deep cleaning the whole car until you've checked your cabin air filter. People forget these exist! It's usually behind the glovebox. If you've been driving through dusty outback tracks or just through the city, that filter gets clogged with pollen, dust, and mould. I reckon 50% of the 'musty' smells I deal with are solved just by chucking a new $30 Ryco filter in. It takes two minutes, no dramas.

UV rays are brutal on your dash, but they also bake smells in. If you've got a funky smell, don't leave the car sealed up tight in the sun. If you've got a secure garage, leave the windows down a crack to let it vent. But here is the pro tip: if you've shampooed the carpets, they MUST be 100% dry before you seal the car up. I once rushed a job on a black Commodore and left the floor slightly damp, next day it smelled like a swamp. Use a wet-vac or a fan to get it bone dry.

If you're on a budget, don't waste your money on those expensive 'bombs' first. Grab a tub of bicarb soda from the supermarket. Sprinkle it liberally over the carpets and seats, leave it overnight (or at least 4 hours), and then vacuum the living daylights out of it. It’s an old-school trick, but it genuinely pulls odours out of the fabric better than most fancy sprays.

For the really tough ones, like heavy tobacco smoke or that 'wet dog' smell that won't budge, I use an Ozone generator. You've gotta be careful with these (don't leave pets or plants inside), but it’s the only method I trust for deep sterilization. Run it for 20-30 minutes with the AC on recirculate, then air the car out for an hour. It'll smell like a lightning storm, but the funk will be gone.
