Has anyone tried it? I bought some to eliminate the musty stink from the vents. But I’m hesitant to use it. It foams up the ducts. I’m concerned about what the foam might do if it leaks elsewhere. Also, I don’t want the climate control system to forever smell of cleaning fluids. I did this to a pair of shoes once and then threw them away because the chemical stink was worse than my own. I don't want to throw away my Porsche.

 

Phil from Detailers Domain uses the Klima system. He could help you out.
