nextzett Klima Cleaner ETU - Aerosol Cabin Air Freshener and HVAC Odor Remover - Easy One-Step Application for Fresh, Clean Air - 3.38 fl oz (100 ml)

Ok, let me give a brief description of what needs to be done (Windows must be closed): Get paper towel and place it on passenger side floor, push seat all the way back, place can on top of paper towel, turn car on and turn AC on at highest fan setting. Depress top button on can until it clicks and close door. Wait at least 12 minutes. (Can will stop spraying before that) then open doors and windows down to ventilate car. You will notice a strong chemical type of smell, this is normal. Wipe away any little excess product on the air vents of your car. And....your done. Its really simple and after the chemical smell fades in a couple of days, ALL smells are gone!!!! My interior smelled great afterwards and the musty smell that was there disappeared completely.I highly recommend this product for musty or any bad smell from your AC and interior. Its been over a month and still no signs of smell.

I received a can so small its useless for the intended purpose. I would have to use 4 cans just to equal the previous size of the old can. Waste of money.

So i've determined that this is basically lysol on super steroids!! It does a great job, but do this when you have the time to leave the windows open afterwards for most of the day to air the car out. I did this in the evening then had to drive to work the next morning and ended up driving down the interstate the whole 20min ride in with the windows down and even then it was still strong when i got of work later in the day. Also wipe the residue off afterwards from the dash, and lay a towel under the can since a good amount of it settles on the rug around the can and soaks it. All in all, it's a great product, but i would only use it for extreme cases when your car smells mailnly during recirculate. If your vents smell when not in recirculate, try spraying lysol through the intake under the hood first. It will be less strong, and will accomplish the same thng. If that doesn't take care of the smell, then move to the foam, then to this as a last resort.

I use this product for the first time. I love they finished product it leaves the car smell fresh immediately. Easy to use. I will buy it again.

Used the bottle as instructed. The cleaning liquid, vaporised, seems to make it into the AC system as I saw liquid dropping out of the AC underneath the car. But after 2 weeks the smell is back. I will try out the other system from einszett where you insert the cleaning liquid with a little hose into the car.

The air conditioner in my truck had been smelling moldy and mildewey for quite awhile and I didn't quite know how to solve the problem. After some online searches I finally stumbled upon great reviews for this product. I purchased it, followed the directions, and sure enough, it solved my problems. It does leave a strong chemical odor in your car for a few days which eventually tones down to a citrus-like smell. But this smells WAY better than the mold and mildew smell which constantly irritated my sinuses and caused me allergy issues. This product is worth every penny.

There was a broken sprayer, it was discovered at the beginning of work, a huge puddle formed in the car, the smell disappeared during the day

They aren't kidding when they say "may cause dizziness" so pay attention to the instructions. My car switched itself out of Recirculate halfway through the treatment, and my street was briefly filled with "dizzy gas". Not what I expected! It may have helped my A/C issues a bit, but not completely, probably due to the incompleteness of my process. I might try the other foam product from the same company.

Did not get rid of smell.

Freshened the a/c system a bit but did not completely remove humid odor
