I cannot believe I'm even asking these questions - one because I know I'm going to be grossed out and two because it will expose my ignorance on hood stuff - but is that stuff as gooky feeling as it looks? How long does it take to get like that? That is actually grease/fat buildup that is sucked up by the exhaust fans, right? How do you clean the ones in your own house or please, just tell me that house ones don't get like that!
