There was a problem filtering reviews right now. Please try again later.
2 weeks later the damp musky smells are back. The strong fragrance was just masking them, not killing bacteria. The product claims to kill bacteria but in my experience it doesn’t. I therefore cannot see any reason for buying one.
I will use a Holt a/c cleaner aerosol next time. I have used them before and they DO work well giving lasting relief from damp a/c smells, plus the fragrance isn’t over powering.
Shop elsewhere.
When it arrived I used it straight away.
All done as instructions said.
When i turned on my a/c i had mild smell of muld/dump... After i used this "cleaner" for a week after use i had overwhelming scent of bleach. So i used my heater and a/c only with opened windows, what didn't make any point in heating, cooling down. It was only for getting rid of that overwhelming scent.
Yes, that muld/dump disappeared for a while it was strong smell of bleach...
Even after couple weeks after use , scent of bleach didn't disappeared and muld/dump smell coming back , not same , but coming back....
In conclusion i would say that this spray just made overwhelming scent for a couple weeks and did absolutely nothing for getting rid of initial problem . I strongly believe that soon as that bleach smell will be gone , that muld/dump smell will come back in full.
Waste of money - wouldn't buy it again
I've marked it as 4 star overall as I cant say how effective it is against bacteria within air con system.
It's very simple to use. You need to follow the canisters instructions and time it.
The smell afterwards was rather heavy , and reminded me of a Male deodorant to be honest, but is fresh and pleasant. I would not wish , or reccomend sitting in the vehicle immediately as you need to let some air flow around and not inhale the product.
Great value , currently on a promo.
Would certainly buy this again, process took under 20 mins and no tools or messing with air filters/ behind glove boxes needed.

I've seen a few negative reviews and I can only guess that their cabin/pollen filter was also in need of replacement. This deodoriser can't be expected to fix that problem.
I'll use one of these again in 12 month's time.
Please remember that a product like this is for air con maintenance and not a fix for an air con system that could need parts replacing due to it working insufficiently or producing a bad smell due to an already developed bacteria build up within the system itself.
Pros: Does the job.
Cons: Powerful after scent/fumes.
The Reviewer.
It's not terrible but my car does now smell like a teenage school disco.
It reminds me of Lynx Africa and it's very strong.
But it seems to have done the trick and the aircon no longer smells like feet!
