The Science Behind That New Car Smell

Everyone loves that “new car smell,” but few know what actually causes it — or how to maintain that fresh scent as your vehicle ages.

What Causes the Smell?

It’s a mix of chemical compounds (called VOCs) released by the materials in your car — the plastics, fabrics, glues, and leathers.

Why It Fades:

As your car ages, those compounds stop releasing. Everyday life — food, drinks, pets, smoke, sweat — replaces the fresh scent with less pleasant odors.

How Detailing Helps:

A deep interior clean removes embedded particles and bacteria from carpets, seats, and vents. Leather conditioning restores that supple, fresh feel. Odor treatments neutralize smells at the source.

Pro Tip:

While you can’t truly recreate the exact factory smell, detailing gets you as close as possible to a clean, fresh interior.
