Causes of Dead Animal Smell in Cars
- It is common for small animals like mice and rats to crawl under the hood for warmth. When the car is turned on or the animal dies, it can cause a bad smell.
- The smell can worsen if the animal dies near the ventilation system.
- Keep an eye out for small animals near your car, especially in the winter.
Removing the Dead Animal Smell
- Remove the source of the smell by searching for the dead animal under the hood. Wear gloves and a face mask.
- If the animal is nestled or tangled in the car’s machinery, it’s best to take the car to a professional for removal.
Eliminating Persistent Odor
- Once the animal is removed, the smell may still linger. Tackle the smell by cleaning the affected area.
- Use commercial disinfectants or homemade odor neutralizers such as baking soda, activated charcoal, white vinegar, and ground coffee.
- If the odor lingers, take the car to a car wash and ask for a thorough cleaning.
