Yeah, Like now U see behind all the charm that dudes are slobs. I mean, like I'm working on it, but I have to, since I live with my uncle, a neat freak, I mean its only necessity that forces change. Do NOT start cleaning up for him. In fact, if I were U, I would even make a stand that dude has to start living a cleaner more diligent life if he wants to be with U. U do not wanna start this relationship and then like it goes long term and he gets comfortable being a slob. Men do NOT change, U have to initiate a new behavior by making a stand that U will not stand for him being a slob. Sounds like though he's not as bad as your ex. Still, I would make this an issue to confront early before it just becomes accepted or habitual.
