How to Get Rid of Bad Smells in Your Car

Getting into your car to a bad smell is embarrassing, especially with passengers. The first instinct is a new air freshener, but fresheners only mask odours – and the mix can be worse. The real fix is to reach the source.

Common Odour Sources

1. Food, milk and juice spills under seats and in the carpet.
2. Damp carpet from a water leak or wet mats – leads to mould.
3. Smoke absorbed into fabric and the headliner.
4. The A/C: the evaporator stays wet and dark, so bacteria and mould grow on it, giving a musty "wet socks" smell when you switch it on.
5. Pets and sweat on the upholstery.

Cleaning at the Source

1. Empty the car and check under seats, in pockets and the boot.
2. Vacuum thoroughly – carpet, seats and boot.
3. Clean the source with an odour-neutralising cleaner: Interior Cleaner attacks the cause instead of masking it; detailing shops can use the concentrate with an extractor for carpets and seats.
4. Dry completely: leave windows open somewhere safe or run the A/C – trapped moisture brings smells back.
5. Mats: rubber with Road Ready, carpet with Interior Cleaner, then dry in the sun.

A/C Odour

• Replace the cabin air filter – typically every 12 months or per your manual, sooner in dusty climates.
• Simple habit: switch off A/C cooling and leave the fan running for two minutes before you arrive and switch off, so the evaporator dries.
• If the smell persists, have the evaporator and ducts cleaned by an auto A/C specialist.

Quick Tips

• Baking soda sprinkled on dry carpet overnight and vacuumed in the morning absorbs odours.
• Clean the inside glass with Glass Cleaner – smoke film on glass holds smell.
• Once the smell is gone, use a light freshener only if you like one.
