Normfest AC cleaner requires AC Off but a cold setting?

[Craiglxviii]

Not only smell is improved, but I did meet to a guy who cleaned corporate ac systems. According to him, ac systems can harbour real nasities like legionaires disease. Etc. Obviously he was egging it on, but one can appreciate the concept.

Probably a similar issue here and the owner spent months about at a time, so the car may have sat undriven!

No egging at all, legionella is an inherent hazard in large AC systems. The whole US DoD had to be cleared out for 3 weeks a few years back due to this, they had a big stagnation volume in the AC system which trapped a whole load of infected particulate matter. Whole lot got ripped out and it dislocated their defence procurement agency for pretty much the whole year.

Well he was making a ton of money. As he said, if any major company had an issue, money was no object solving it.

Used the Normfest Viral one shot - surprised the carpet infront of it was wet!

Has anyone used this, if so did it send out a gas or a sort of liquid spray.
Th carpet was pretty wet and so was the vents of the air intake under the glove compartment in the passenger footwell. It was a slightly sticky wet feel. :-/
Hope it hasn't wrecked the comination pollen filter, but not sure where that is on a CL500

Luckily I had the overmats in .. I could see fine droplets all over it.
Enough for me to get that out , and sort of wipe it on the drivers overmat.
I then ran the car for another 20 mins with the blowers on full. And the plastic vents have dried off and so has the over mats .. almost.
But the actual car carpet is still wet in the area above where the overmats covered.

Not sure what to ... other than not drive it with the heater on and open the windows to air the cabin.?

Realy good job I didnt put it in the centre pointing at the command system,,, that would have been soaked.

The can and instructions didnt say shake the can, so I didnt , but when I could see through the window this spray of liquid. I did open the door and give the can a few shakes, but it still kept pouring out a fine liquid mist spray.

Is that normal?

Did you shake your can?

 

[Craiglxviii]

I don't recall whether or not I shook the can, I followed the instructions. The spray came out as a fine mist and I had no problems with anything being wet.

Thanks Craig
No this is well wet. I even got a ******* towel and wiped the 1" wide stripe of carpart above where the over mat reached to, and 40 mins after doing it, one piece of ******* towel was translucent with the stuff so pretty dam wet.
Interestingly there was a slight carpet colour bleed onto the ******* towel.

Hope it didnt knacker any sensitive electronics up there.

Eurocarpats are going to speak to Normfest and see what went wrong.
They say it should be a fine dry mist.
And are sending me another can :-/

Hope it drys out.

Ecp do another Normfest ac cleaner, I have used it twice this year.

Engine off and just squirt aerosol into all the vents and also open bonnet and put some down the heater intake vent.
I then leave the car for twenty minutes and then go and start it and put it on recycle /cold and let it run for about four minutes and thats it.
It costs slightly more than the one shot but there is enough to do the car at least four times.
I did look at the one shot but presumed that was best used only if the system was badly infected.

Thanks,
Interesti g you thought the ine shot was the stronger version, I did it because ai thought it was the weaker one lol
I.e. Not directly down all vents , and ai thought less invaisive

Yeh I presumed because one shot constantly sprays out and fans running it got pushed into every crevice and therefore was the most potent.

Hmm see the logic, except probably most of it went on the carpet in my case lol

I've used only two types, one is allegedly antibacterial, buts it more like a perfume and within 2 weeks same smell is just about evident

on the S500 I used one that specifically said remove the pollen filters first (very easily done with a couple of screws above where your feet sit in passenger footwell). This was a liquid and you could literally spray direct on the evaporator (once you got a torch out and looked) it didn't work either on both occasions I used it. Couldn't find any other air recirc infeed for the rear AC either.

The best cure is heavy use of the AC system (in my experience over 15 years, seems high humidity and lost of use I guess washes the filth off the evaporator far more efficiently than these silly money pit cleaning products) and to keep it happy never turn AC off
