You must spray the foam with a special foam applicator inside the air vents orifices until you see the foam coming out of them, you must do that with each one of the air vents.

The special has an active ingredient that will remove the dirt and kill all the microorganisms that have found a place there.

These foam will turn into a liquid and will drip eventually through the vents down.

After you manage to insert the foam in all the air vents, you must leave it to activate and work on the surfaces.

After the time runs out, you can start the AC on the max speed to ventilate all the air vents and remove any remained solution.

With the windows closed agitate and let the diffuser sit near the lowest air vents and to spray all the content in all the car.
