Steam cleaning vinyl

I've always thought heat and vinyl don't mix but it seems steam cleaning is normal practice for many LP lovers, among whom I count myself. I've not gone down that path, being happy enough with double washes on my VPI 16.5 for most records but this video shows a combination of both. Upon hearing it (not even watching it) my wife declares definitively that I have fallen among the crazies...wonder what took her so long to notice -- I could be one of these people
