My AC is on all the time but sometimes when i first start up in the morning i get a slight smell that goes away after a few minutes. The car was lying up for a week recently and smelt like a sock for 10 mins after start up.
 
AC bomb should sort it out. My last car smelt like camel breath coming out the vents, one of these sorted it out!!
 
Air Con Cleaner, its made by Comma, all you do is slide the passenger seat the full way forward and position it on the floor near the in the rear passanger foot well.

Then start the car and put the aircon on full tilt and make sure that the re-circulation setting has been turned on. Then set the can of cleaner off and leave the car running for 10 minutes with all doors/windows closed. I will be doing my Cupra tonight as it needs doing also after 3 years and 34k lol.


Tried one of these yesterday - will be interesting to see if the stink goes away although more likely to have the heater on today with the weather in Norn Iron :cry:
