How To Properly Clean Car Air Vents

So, here are the steps you should take to clean vents properly. Some detailers do it differently, but in my opinion, this is the quickest and simplest method.

What you’ll need?

1. Vacuum The Vents

The first step in cleaning your car’s air vents is to vacuum them. Vacuuming the vents helps remove any loose dirt, dust, or debris that has accumulated over time. This preliminary step ensures that the cleaning process is much smoother and more effective later on.

Start by attaching a small brush or crevice tool to your vacuum cleaner. Gently brush the vents while vacuuming to dislodge any stubborn particles. This will make it easier to clean the vents thoroughly in the following steps.

Remember to be gentle and avoid using too much force to prevent damaging the vents.

2. Spray APC on The Longer Brush

To thoroughly clean the air vents, you’ll need a longer brush designed specifically for reaching deeper into the vents. An all-purpose cleaner (APC) is an effective cleaning solution that can help break down dirt and grime within the vents.

Instead of spraying the APC directly into the vents, spray it onto the longer brush. This method not only saves your product but also prevents the cleaner from spreading to unwanted areas. Ensure that the brush is damp with the APC but not dripping wet, as too much cleaner can potentially cause damage to the vent components.

With your APC-dampened brush in hand, you’re ready to proceed to the next step of the cleaning process.

3. Agitate Vents With The Brush

Now that your longer brush is prepared with the APC, it’s time to gently agitate the vent slots. Insert the brush into the vents, reaching as deep as possible to remove any hidden dirt and debris. The long bristles will help clean even the hard-to-reach areas within the vent system.

Make sure to slide the brush in all directions, including up, down, and side to side. This ensures that you clean the dust from hidden places and crevices within the vents.

Be cautious not to apply too much pressure, as you don’t want to damage the vent components. A gentle but thorough agitation with the brush will effectively clean your car’s air vents.

4. Clean The Excess APC With a Microfiber Towel

After agitating the vents with the brush, there may be some excess APC left on the surface. To remove the remaining cleaner, gently wipe the vents with a clean microfiber towel. Microfiber towels are ideal for this task, as they effectively pick up leftover dirt and dust without causing scratches or damage.

Carefully wipe the vent slots and surrounding areas to ensure that all excess APC and dislodged dirt particles are removed. This step will leave your car’s air vents looking clean and shiny, free from any visible dirt and grime.

You won’t be able to dry the whole area thoroughly, but we’ll go through that in step 5.

5. Use a Second Brush To Dry Vents

Even after wiping the vents with a microfiber towel, there might still be some leftover APC. To completely dry the vents and remove any remaining cleaner, it’s a good idea to use a second, clean detailing brush.

Gently slide the dry detailing brush through the vent slots, reaching as deep as possible to absorb any remaining moisture.

This step ensures that your car’s air vents are not only clean but also completely dry, preventing any potential mold or mildew growth.

EXTRA TIP: Use a Steam Cleaner For Very Dirty Vents

In some cases, you may encounter extremely dirty air vents that require a more intensive cleaning approach. For these situations, I recommend using a steam cleaner to help break down stubborn grime and dirt before proceeding with the rest of the cleaning process.

Start by carefully applying steam to the filthy air vents, ensuring that the steam cleaner is not too close to the vent components to avoid causing damage. The steam will help loosen the dirt and make it easier to remove in the following steps of the cleaning guide.

Once you’ve used the steam cleaner on the vents, continue with the vacuuming, APC application, and agitation as described in the earlier sections. This extra step will ensure that even the dirtiest vents become sparkling clean and free of debris.

How To Remove Bad Odor From Car Vents?

After you have successfully cleaned car vents, there might still be some bad odors coming out of them.

Although this is a pretty common problem, it’s easy to fix it. 

If you’re a professional car detailer, this is a great way to earn some extra money by adding this option for your clients.

For this, you’re going to need some high-quality odor remover. I recommend you use this Turtle Wax Odor-X Multi-Surface Cleaner (check the price on Amazon now).

Follow these steps to flush the AC system:

  1. Turn on the car, turn the AC, and press the Recirculation button
  2. Close all the windows
  3. Put the can between the front seats – usually, the armrest is the best position.
  4. Open the can, and push it – it will lock automatically.
  5. Close the car doors, and let it work for 15 minutes.

After 15 minutes, you have an odor-free car that smells great. And air vents are entirely cleaned from any bad smells. 

However, don’t forget to remind your clients to change the cabin filter. I realized that many people don’t change it often enough, and usually, it’s the most common reason for bad smells coming out of air vents.

Why It’s Important To Clean Car Air Vents

Let’s see some essential reasons why you should regularly clean the air vents in your car.

Cleaning your car’s air vents is an essential part of maintaining a comfortable and healthy driving environment. Here are some key reasons why it’s important to clean your car air vents regularly:

  • Improved Aesthetics: Dirty air vents can ruin the overall look of your car’s interior. Regular cleaning keeps your car looking fresh and well-maintained, ensuring that you feel proud every time you hit the road.
  • Preserving Car Components: Over time, the buildup of dirt and grime can cause the plastics in your air vents to fade or become discolored. Cleaning the vents helps preserve their appearance and prevent potential damage.
  • Health Benefits: Dust, allergens, and bacteria can accumulate in your car’s air vents, negatively impacting your health. Regularly cleaning the vents reduces the risk of respiratory issues and ensures a healthier driving environment.
  • Odor Elimination: Smoke and pet odors often linger within air vents, leading to an unpleasant smell in your car. Cleaning the vents helps remove these trapped odors, providing a fresher and more enjoyable driving experience.

Even if we forget about the car’s look and the bad odor, we can’t forget about our health. 

It’s essential to clean the vents properly. That way, riding is entirely safe for your health and won’t cause any respiratory problems or allergic reactions. 


Taking the time to clean your car’s air vents is a small investment that can make a big difference in your driving experience. By following the steps outlined in this guide, you’ll be able to enjoy a clean, fresh, and healthy ride every time you get behind the wheel.

Remember, a healthy ride is the best ride. Not only will you improve the appearance of your car’s interior, but you’ll also create a more comfortable and safer environment for you and your passengers. So, don’t wait any longer—grab your cleaning supplies and give your car’s air vents the attention they deserve.
