Einszett Klima Cleaner
has anyone successfully used this on a E90? I tried going down the center vent, but I can only get approx. 10 cm in, there is something blocking me from going further. Side vents are OK, but I'm afraid they're connected to the footwell vents, so anything down those will just drain out into the footwells.
Also, the BMW TIS for aircon disinfection states you should remove the front underbody protection before you disinfect - why so?
Any help greatly appreciated!
