Place 2KG of baking soda in a plastic box without covering it, then put it in the trunk. It should absorb the odor within about three days. First, give the car a thorough cleaning to wash away all the dirty water, then go to the supermarket to buy some bagged activated carbon or charcoal and place it in the car. Take the car to a car wash shop for a complete rinse from inside out, and place a can of strong-scented air freshener in the car.

What to Do When the Car Key is Inserted Backwards and Can't Be Pulled Out?

Pour cooking oil or engine oil into the keyhole, then gently and slowly pull it out. If pouring oil doesn't work, find a hard object to tap slowly inside the lock, then pull it out gradually. If both methods above fail, you can only call a locksmith and seek professional help to unlock it. For keys with similar top and bottom holes, you can mark one side of the key to prevent the key from being inserted backwards and getting stuck in the keyhole.
