When you get into your car, have you ever noticed a bad smell? If so, you are not the only one.
Mold growth in the cabin’s vents is frequently to blame for the vinegar-like smell that car air conditioners produce. You should be cautious because it might be a sign that mold is developing inside your air conditioner.
There are a number of possible causes for this, but fortunately, there is a simple solution to remove the vinegar odor from a car. Continue reading to learn how.
Why Your Car Smells Like Vinegar
Your car’s offensive odor could be a sign of a number of problems. Either there are broken parts, or the vehicle is dirty. To properly get rid of the smell, you should first inspect the source. Here’s a list of the most common causes of sour smells in cars:
1. Mold and Mildew
Mold and mildew are the most typical culprits behind that musty, dingy odor inside of cars. Conditions that are moist or humid will cause mold to grow.

This is probably the reason if you’ve ever spilled anything inside your car, be it juice, soda, water, or any other liquid, and you didn’t let it air out. Additionally, if your car experiences temperature or seasonal changes, which typically occur from winter to spring, it may also occur.
Your car vents will also start to smell musty. Turn off the air conditioner if it is running and you can smell vinegar.
If turning off the air conditioner eliminates the vinegar odor, mold that has grown in the cabin filter vents is probably the cause of the odor. Dust that gathers in the air vents throughout the year may be to blame for mold growth.
The air conditioner may not be working properly if the smell persists after you turn it off, and you may need to clean your cabin filters.
2. Food Left in Your Car
Remains of food in your car can give it a pungent smell. When you’re on the go and hungry, you might unintentionally leave food in the car for a long time, allowing it to rot, start decomposing, and release a lot of acidic compounds that give off a vinegar-like odor.
The best solution is to search your car’s floorboards, underneath the seats, cargo nets, and other storage areas for the food so you can eliminate the odors. When cleaning, it is best to wear gloves to prevent direct contact with spoiled food.
3. Fluid Leaks
Things that are acidic are usually in the car when there is a vinegar smell. Your car’s battery should be the first thing you check since it is one of the most acidic components. Hydrogen sulfide emissions, which also have a vinegar or rotten-egg odor, are produced by battery acid because it is a relatively flammable substance and contains sulfuric acid.
Your car may leak sulfur gas if certain components, particularly the catalytic converter, show signs of wear and tear or are improperly connected. If anything is dripping from the battery of your car, you’ll need to get a replacement.
A gas leak is another factor that contributes to your car’s vinegar odor. Rarely, but occasionally, vehicles’ fuel lines may become leaking in some unspecified location. And when it does, the stench of skunks permeates the air conditioning as a result of the strong gas smell.
In addition to being disgusting, the smell of gas can be dangerous for the driver and other passengers. So if you notice a battery acid leak, it’s best to have a mechanic look at your vehicle.
Decaying Organic Material in Car
The other likely reason for the smell in your car is a buildup of leaves and other dead animals like a rat or lizard. When you turn on the air conditioner after they begin to rot, you will smell the odor.
While it is simple to remove leaves by hand, it can be challenging to get rid of a dead animal, particularly if it is lodged in your cabin air filter or another difficult-to-reach location. A professional is required in this situation.
Vinegar Spill
Vinegar has a history of being the main smell-causing ingredient. White vinegar is a typical household item that is used for cleaning and as a natural cockroach deterrent in vehicles. You could accidentally spill this product while using it, leaving your car smelling bad.
Find a box of baking soda and empty half of it into your car, preferably underneath or close to the area where the vinegar was spilled on the floor mats or seat cushions. This will solve the problem. Then vacuum it up and repeat after letting it sit for a while.
Alternately, use a sponge or plastic brush to scrub the area where baking soda has been applied, working the baking soda into the surface before rinsing with clean water.
Rocks from volcanoes or coffee grounds are other options.
