The Cause of the Car Cabin Smells, This Trivial Habit is the Source

If there’s one car odor you should never ignore, it’s exhaust fumes inside the cabin. Exhaust fumes in the interior of your car most often indicate a leak in your car’s exhaust system or poor seals on your windows or doors.

Oddly enough, this is why the car cabin smells so strong.

Check the cost, the reason is trivial things that car users usually do.

If your car cabin smells strong, the following five reasons are usually the main ones.

1. Never clean the air conditioner filter
This appliance emits a pungent odor if it has never been cleaned.

This is due to “a buildup of dirt or dust in the A/C filter device. It gets worse if you add bad habits like smoking or opening the windows while driving.

2. Leftovers in the car

The smell of food absorbed by the air conditioning over time will cause an unpleasant odor, especially if the food has a pungent smell.

In addition, crumbs of food falling out will invite small insects into the cabin of the car.

3. Cigarette smoke sticks inside.

“Cigarette smoke can stick to the entire cabin of the car, and over time cause a very unpleasant smell,”

Even worse, when the smoke from these cigarettes is distributed by the air conditioner, it will make the cabin smell even more musty.

4. Do not expose the car to the sun for a long time

A car left in the garage long enough makes the temperature in the cabin get humid.

“Especially if there are wet parts inside the car, it will emit an unpleasant smell when the car is parked in the garage for a long time,” Dimas warned.

5. Car perfume yawn

Car perfumes with liquid ingredients contain chemicals that can evaporate when exposed to heat.

These chemical fumes enter the wet HVAC line and slowly release a pungent, sour smell.

How to prevent unpleasant odors and mold from air conditioning

Your first task is to find the drain tube in your vehicle and make sure it is functioning properly. You may want to take your vehicle to a trusted dealer or repair shop to prevent further damage to your vehicle.

If the drain pipe appears to be in good working condition, you can rule this issue out and consider removing the mold present in your A/C system and preventing new mold from forming in the future.

Here are a few ways to do it…

  • Turn off the AC 2-5 minutes before turning off the car but leave the fan on. This will allow the entire A/C unit to dry out each time you use it.
  • Clean or replace the air conditioner filter. A dirty air filter reduces airflow through the air conditioner and helps maintain humidity inside the unit. Be sure to replace the AC filter as often as recommended by your vehicle manufacturer.
  • Spray disinfectant into the exterior vents (where your car draws air from the outside into the car). Make sure your air conditioner is set to a setting that draws in air from the outside in, so the mist is drawn into the ventilation system and can work directly to kill mold and bacteria.
