Methods to get weed smell out of car vents

Here are three ways you can get rid of weed smell from your car vents.

Use an air-conditioner treatment spray 

This method involved using a spray designed to clean and freshen up the air conditioning system in your car. The air conditioning treatment spray will neutralize the odor molecules lingering deep in the car vents. 


  • A reputable air conditioner spray 
  • Microfiber cloth 
  • Vent cleaning brush
  • Additional odor neutralizers, if necessary


Once you have all the materials, park your car in a well-ventilated space. Then, open all the windows and doors for maximum airflow.

  1. Start by locating the air intake. In most cars, it’s found at the top edge of the hood near the windshield. 
  2. Using the vent-cleaning brush, remove any debris stuck inside the air vents. 
  3. Once you’re done, read the instructions on the back of the bottle for how to apply the spray. 
  4. Then, start the car and turn the air conditioning system to full blast. Allow it to run for 10 minutes to expel all the odor molecules inside the air vent. 
  5. You can repeat the process with an additional odor-neutralizer to completely remove any lingering smell. 

By now, you should have a fresh, clean vehicle ready for your next drive. 

Use activated charcoal

Activated charcoal absorbs and traps odor molecules in the air and is available in small porous bags.

Place the activated charcoal strategically around the car, especially near the vents. Turn on the AC system to expel the weed smell inside, which the activated charcoal will absorb. 

Repeat the process if necessary. Then, allow the charcoal to sit for a few hours or overnight to absorb any lingering smell inside your car. 

Once satisfied with the results, remove the sachets and wipe down the vents to remove any residual smell. 

You can also use baking soda instead of activated charcoal to absorb unwanted odor molecules in your car. The only difference is that you’ll need to vacuum your car’s interior to remove any remaining loose residue. 

Deep clean your car

Is there still a notable smell in your air vent, even after using the above methods? Then, it’s time to deep clean your car with a professional

An expert will clean your vents, upholstery, carpet and other interior accessories where weed smell can linger, leaving you with a clean and fresh-smelling ride.

How can you prevent weed smell in your car?

Remember the adage: prevention is better than cure. Here are ways to avoid weed smell in your car vents in the first place.  

Roll down windows while smoking

Opening windows while smoking or transporting weed helps fresh air circulate and reduces the chances of odor buildup. You can also avoid smoking inside the car altogether.

Store weed in a smell-proof stash box

An effective stash box will help to prevent weed smell from lingering in your car. Additionally, the stash box offers a discreet way to store your weed inside the car to avoid drawing any attention. However, it’s crucial to understand the local laws and regulations when smoking and storing weed in your car. 

Keeping it fresh

Use activated charcoal, baking soda, or an air conditioner cleaning spray to get the weed smell out of your car vent. If these methods are ineffective, you can deep clean your car.
