How to Remove Mice Smell from Car Vents and Upholstery in 7 Easy Steps

1. Identify the source

Finding the odor’s source should be your first priority. Usually, a dead mouse or mouse droppings are the source of the odor. To get rid of the mouse or clean up the urine and droppings, you must locate the precise location. By using the smells in your car, try to find the specific location. Finding the mouse shouldn’t be too difficult because the odor will be strong.

Possible mouse hiding places

Mice typically prefer to hide close to the engine area because it’s warm, and vehicles don’t have much room for hiding places. It is best to check the space between the front seats and the engine before removing the cowling. Mice don’t like to be seen, so this is a great place for them to hide because it’s frequently overlooked. If there are no mice in that compartment after you check it, you can vacuum and dust it to get rid of extra dirt.

To inspect the area, raise the carpets and take out the seats. Remove every component from the dash and inspect that area as well.

2. Get rid of dead rodents (if there are any).

You must take any dead mice out of your car if you find any. Before touching the mouse, get ready by donning rubber gloves and a face mask. To prevent any pieces from becoming stuck in your car, carefully pull it out. Before throwing the mouse away, place it in a plastic bag and seal it.

You should start by cleaning the area where the mouse was found. Spray some cleaning solution on it, then let it sit for five to ten minutes to absorb it. Once the time has passed, use an odor remover to clean the area.

3. Car preparation

The vehicle needs to be prepared for cleaning. All of the removable car parts ought to have been taken out during step one, which will aid in the setup. However, there are still a few additional tasks you must complete. Make sure the windows are first rolled down. Due to the odor and possible bacteria, it is best to wash the car outside.

Turn on your car and open the dashboard vents to let it warm up.

4. Open the vents

Again, make sure you are wearing a mask and gloves because this part can be messy. Turn on the heat in the car and open the driver’s door.

Depending on how much dirt and debris is lodged in the vents, this step may take a minute or longer. Given how much dirt our cars gather when they are in use, you ought to see a wide variety of items emerge. Slide the temperature up and down once nothing else is coming out of the vents. You can then make sure there is nothing else in the vents.

5. Fumigate

You must fumigate the vents after making sure nothing else is coming out of them. Although you can remove mouse droppings from vents by blowing them out, some vent components may still be saturated with urine.

Spend money on a fumigating agent, then spray it into the vents. After spraying it, let it react and finish the job. In addition, you could use vinegar or bleach in place of fumigating fluids.

6. Clean the chairs

As the foam can absorb the urine of the mice, getting the smell out of your car seats can be difficult. We suggest moving the chairs outside, soaking them in vinegar, and setting them aside to dry in the sun. That will disinfect your seats and kill any bacteria or germs that may be on them.

If necessary, carry out this procedure two or three more times until the odor is eliminated from the seats. No matter how frequently you perform this step, vinegar won’t harm your car seats in any way because it is a natural ingredient.

7. Final adjustments

Last but not least, disinfectants should be sprayed on any surfaces that can be touched. After a few minutes, clean the area. If necessary, use a steam cleaner or a vacuum to ensure that all surfaces are free of dirt and bacteria. When everything is finished, there shouldn’t be any unpleasant odors coming from your car.

Additional Advice and Techniques

The best way to avoid unpleasant mouse odors in your car is to prevent the odors from developing in the first place. Consider the reason the mice or mice entered your car. Are you keeping trash and leftover food in your car? Is the cleanliness of your car always impeccable? Try to do regular maintenance on your car to make it less likely that mice will get in or, at the very least, to keep them from getting in.

If you see mice in your car, use rodent repellent to keep them away and prevent them from returning. Don’t put rodenticide in your car because mice may eat it and die somewhere hard to get to.

You could also have a mechanic work on your car, but keep in mind that this could be an expensive task. The majority of mechanics bill by the hour, and it might be challenging for them to find the mouse. Therefore, try to finish the job yourself if at all possible. Although it may be exhausting, at least you will have some money saved.


It can be challenging to deal with mice and unpleasant mouse odors in your car. However, if you use the cleaning method we recommended, you should have no trouble getting rid of the odor. Be persistent, and once you’re done, use prevention techniques. You can be certain that mice won’t be able to access your car after that.
