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)

The only a/c deodorizer that actually worked for my BMW 3 series. I have tried BG frigi-clean, Dynamic stuff, a/c cleaner from Homedepot, even eisnzett's own foaming agent, nothing lasted longer than 2 weeks. This spay smells really strong and it is. Recycling it in my car for 5 mins and the sour a/c smell has been gone for 1 month! I will see how long one shot will actually go and update here. Two things you need to be cautious about:1) don't place it directly under your glovebox because that will leave white residual on the glovebox cover as the mist shoots upwards and his the cover, also it will condense and drip to the floor. Do yourself a favor by pulling the passenger seat all the way back and put the can where nothing obscures its path. 2) as mentioned before, the smell is really strong, I would recommend you leave the doors open overnight after the treatment. It actually took me 3 days to get rid of the smell.

As the name implies, it is easy to use. It worked well in our small SUV, which had a faint "moldy" odor (I suspect from the heating/AC unit). Use just requires you to close the windows, start up the AC on high, and activate the can. After the can was finished and the car was aired out for a while, there was a slight residual "fresh" smell (not unpleasant). In my case it wasn't a permanent fix, but it did keep the vehicle odor free for 3-4 months.

After reading the review I thought it would be good at removing odor. Unfortunately, It didn't. Earlier this summer I got this stinky mildew from the air vent, so I think it may be the time to clean the A/C. Since I am not really a professional mechanical expert, I purchased the East-to-Use one with this. Plus, I got a new air filter. According to the instruction on the professional one, I removed the blower and air filter, applied it directly on the evaporator core, and waited for 20 mins. then I turn on the A/C to dry out the core. Everything seems fine that day, stinky smell is gone, and air is refreshing. However, it did not last long. I got those stinky smell second day. So I used the ETU version. That one wet the may, left some residue on the seats, gave this unbearable smell, yet did not remove the mildew odor. So I guess I will never buy any product like this.

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.

Excelente

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.

My car was smelling musty, almost moldy especially when the AC was NOT on. I went by the reviews online and purchased this. SO glad I did. It was super easy to use. My car had a bit of a chemical smell for a day or two so if you can avoid driving it immediately after using, do so. Now it just smells clean with or without the AC on. So grateful for this product. I can highly recommend it.

Did not get rid of smell.

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