Why Does the Car Smell Bad Inside?
2 Answers
For example, eating or smoking in the car can naturally lead to unpleasant odors over time. Below is an introduction to the causes of odors inside a car: Odors from interior materials: Car interiors use a large amount of plastic, rubber, and other materials. The organic solvents and additives in these materials gradually release into the car's environment during use. Odors caused by the cabin air filter: Many car owners report that when the air conditioning is turned on, a sour and musty smell blows out, which is very unpleasant. However, this condition usually improves after some time. In fact, this odor is a sign that the cabin air filter needs to be replaced. The air conditioning system has been contaminated by bacteria, leading to mold growth, and replacing the filter can alleviate the odor.
Recently, the weird smell in my car has been driving me crazy. After careful investigation, I found it was caused by mold in the air conditioning. Especially after parking with the cold air on, the accumulated water in the pipes breeding mold is the worst. Last week, I specifically took out the filter to check—wow, a thick layer of dust mixed with mold spots. And that time when I spilled milk tea into the seat crevices without noticing, a few days later the whole car smelled like sour milk. Now I check under my feet every time I get out. Actually, the trunk is often overlooked too. Last month, I forgot a wet picnic blanket in the trunk, and the moment I opened the car door, the moldy smell almost knocked me out. Oh, and a heads-up for friends who smoke: tobacco tar sticking to the interior for a long time makes that burnt smell particularly hard to get rid of.
