seems a good deal unless anyone knows different?

Surly for it to freshen the car - it needs to freshen the filter / deoderise the system - it needs to hit the air intake for the air lower down?

Ziggy

i reckon you chuck the filter out then spray it in and refit new filter after?

Aldi or Lidl usually have one for a similar price in the summer.

NO NO NO NO NO

Don't do it - I did, and had to buy a new blower shortly after.

I don't know what other cars' blowers are like, but basically the Croma one is like a washing up bowl shape, right under the back of the pollen filter. The fan sits on a bearing in the bottom of it. The air outlet is at the top of it - it's a centrifugal fan.

Anything you spray in will collect as liquid inside it and rinse all the oil out of the fan and gum it up. Mine ran like crap for about a year then gave up, despite a stripdown and deep clean with white spirit and WD40.

The one and only way I can see of doing it is to get a santiser spray that has an outlet straw/tube. Take the foam trim off below the glovebox (not simple, and it's delicate too), then drill a small hole in the output duct from the fan. With the blower on full, squirt it in there, so it's spraying into the air flowing out of the fan but it doesn't actually go into the fan at all. Then plug up the hole with a stopper of some sort to stop it possibly whistling like a flute.

Actually that ECP one looks just the job, and mine's got whiffy in the last week so I might just test my theory.

EDIT: Flipping heck - I just ordered two cans and got free delivery too. £6.78 in total.

Might have a go with the one you've spotted Dave and the one shot plus cleaner as per this link...

I tried one of those one shot type of things in my Croma when I first got it. It achieved nothing. With my old Seat, there was an inlet port on the passenger side, and you could point it into it and detonate and it all went in there. The croma breathes in from the general vicinity of under the glovebox, but there's no specific inlet port. So if you spray in this general area then you'll only get a very low concentration of the germ killer going through the air con - not enough to kill any germs in there.

When I tried it (with anothe brand), it made the inside of the car smell nice, but the yucky smell was only masked and came back after a couple of days.

I'm going to drill into the air duct of mine and intravenously inject a can of the spray that Dave found, but so that none of it gets into the fan.

Right - you won't find this technique in any workshop manual, but I did this yesterday and my car no longer smells like bad breath on startup.

I think the pictures explain the technique fairly well.

• Take the foamy cover off the underside of the glovebox bit.
• Drill a very small hole through the output duct of the blower. I put it right in the centre of the flat area, so a square of sticky tape will seal it after doing this. It slopes downhill away from the fan at this point, so any possible liquid will not run back into it. It also means that the nozzle tube will be spraying downwind. I used a drill bit that was very slightly smaller than the tube and kept trying it then having a bit of a drill-wiggle a few times until it would just go in. If you don't get a tight fit then it may blow the spray back out, due to the air pressure from the blower.
• Spray the spray into all outlets, not forgetting the ones under the two front seats for the rear passengers' feet. Leave for 10 minutes.
• Adjust a trouser belt so it presses the button fully, then leave it adjusted as required and slide it off the can.
• Plug the can into the duct, start the engine and put full cooling "LO", full fan, mono, all ducts (three arrows x2).
• Slide the belt back onto the can, leave the car and shut the door.
• Leave it half a minute, then hold your breath and open up, change it to full heat, full fan, mono all ducts. Shut the car again.
• Leave it a minute more, then open the car and check the can is empty. If so then switch the ignition off and leave the car closed up as long as possible.
• Enjoy driving a car that doesn't smell like wet dogs.
• Don't blame me if you break something by doing this!

I use an ozone generator. Simply close all windows, turn on the air con, making sure the lever is set to recirc rather than pulling air into the car. turn on the ozone generator & let everything run for half an hour.
Kills all living things inside the car & leaves you with that 'industrial freezer' smell.

I've started using it in the bus - I give the floor & seats a good swill with disinfectant cleaner then leave the ozone generator plugged in for an hour on Friday night.
Monday morning, the inside of the bus smells lovely and fresh & clean - ready for some passengers to make it smelly again!

Interesting. Not something I'd heard of before, but it sounds very sensible. Is it the same smell as a laser printer?

Is yours a diddy home one, or a big industrial jobby?

Do you take precautions to ventilate before going back in? It's not nice stuff, especially if you happen to have a passenger with lung problems.

I think it degrades though, from what Wikipedia is telling me? So perhaps it does just need leaving rather than venting.

I think I might have to get me one of them things. They're not even expensive.
