Query: Nothing special

As far as cleaning, I wasn't impressed and that's what I really bought this item for. The portion dedicated to proper set up of your sound system is pretty good. If you have a CD/ DVD player that doesn't get much use and you just want something to run through every now and then, this may work fine, for my truck's CD player, it's not cutting it.
