Musty smell from air vents (not AC) 6R POLO

[RUM4MO]

Yes but this nasty stuff will have spread throughout the out putting ductings so they need some of this atomised sanitiser on them as well, so if the chilled evaporator grabs all this sanitiser spray that will work - it will only be the incoming faces of the evaporator that will end up getting treated. I'd think that normal particle dropout will work better for the complete system sanitising - if the instructions on the bomb say otherwise clearly, then follow them.
