I don't wash them either.... but it seems to me that most of the cheaper ones need to be thrown out every so often anyway, no matter how clean or squeezed out they get

Now you've got me thinking that maybe I should wash the nicer ones! I'm not really a clean freak though in general... I don't clean most of the other toys either if it's only dd that's been playing with them, unless they get really dirty or dusty. I don't do any sort of "routine" toy cleanings.
