InterDynamics Certified A/C Pro Vent and Duct Cleaner, Professional Strength Odor Eliminator for Cars, Truck, HVAC, 10 Oz

This product completely removed the moldy, mildew stench from my car’s AC system as advertised. One important tip: remove all cabin filters (including pre-intake and carbon filters) before using it. Otherwise, the spray just soaks the filters instead of reaching the condenser. If you take that extra step and follow the instructions, it works great. Expect a strong powdery chemical smell for about a day, but once it fades, the original odor is gone for good.

Works well when you properly prepare the car as follows:1. Clean/blow off and wash off that external air intake area prior to applying this.2. The biggest thing people forget is to temporarily remove the cabin air filter prior to spraying this in the external air intake around the hood windshield area. You want this product to go past where the cabin air filter is and reach the A/C system.3. Once you start spraying it into the external air intake, you’ll notice the fumes are pretty strong. Same goes for the inside of the car. I got a little bit of a headache during application, so take precautions.4. You already have the cabin air filter out as part of this exercise, so replace it with a clean, new filter while you are there.After running the car’s A/C system for about 20 minutes, I was concerned about the chemical smell in the car being too strong, so I washed off the external air intake area with the garden hose and ran it another 10 minutes. The results were awesome: the bad smells were gone. I let it sit overnight and drove with the windows down the next day. The chemical smell was very light on day 1 and completely gone by day 2.

Easy to use and smells pretty good.

Been driving around with stale air for a decade in my car. This is a great product. Although lysol works well, this has a smell more fitting for a car interior.Make sure you remove your cabin air filter and let it air out for a day.The smell will be overwhelming if you dont.

Definitely works as instructed. We removed the “in cabin air filter” as instructed and run it through the system and whatever mildew smell that was in the vehicle is long gone - we bought extras and did it with the rest of the fleet just for maintenance and the vehicle smell beautifully fresh something that I never would’ve noticed if I didn’t do it

Easy to use, and helped a little; but the dog smell is still noticeable.

It took a while to get the mice to leave my car but I was finally successful. After changing the cabin air filter, I needed to be able to turn on the air without being hit with the smell of urine left in the ducting. I followed the directions on the can and was very pleasantly surprised that this product got rid of the smell and I'm satisfied that it disinfected as well.

Not sure if this product actually works if it were to spray correctly. Mine would only foam out of the button area so I was only able to get a little of it to run into the air intake. It was out of the return window so I just tried to make the most of it.
