I don't care, because I have a secret weapon. A dude I work with has a brother that details cars...full-time, for a BHPH dealer, and also for anyone who will pay him. He can get ANYTHING clean. I mean ANYTHING. He shows up in a Honda Passport loaded with cleaning supplies, and a crate containing bottles of mysterious concoctions (many homemade and he will tell absolutely nobody what they are)...and no matter HOW bad a car is, it will be spotless in an hour.
His record was a vehicle that someone had forgotten a bag of dirty diapers in. For two days. In August. It's his Passport...he got it for $100. Aside from the slight but ever-present odor of Windex, there is no trace of any smell.
If he can't get it done himself (it's happened a couple times), a case of Sam Adams will get him an ozone generator for the day.
