I diluted some arm and hammer in warm water and washed the hell out of the frig. Now that it's dried there is a nice white powder everywhere, which is good, so I can see it got everywhere. Tomorrow I will wipe it down with water and see what happens.
I have lots of hobbies that deal with refrigeration, cooling and heating so I'm well aware of the intricacies of these devices. First off almost all refrigerators smell plasticy or funny when they're not on. So that goes without saying that the cold has a cloying effect on smells and odors, which in turn makes mild smells inconciquential to the grand scheme of things. I'm sure if I turned the frig on that I wouldn't smell anything, but I'm anal I want no hint of anything. Let's say I age a new cheese and there's an off taste 3 months down the road I want to be able to say with conviction that it wasn't the aging enviornment.
