What do you think? The toilet(s) need to be checked before and after every revenue flight (at least). Sometimes a wipedown is needed, sometimes a bit more. You get used to it and you simply wear latex gloves if you feel overly disgusted of what you find there. But as I wrote before: if this is a significant thing in the back of your mind, maybe do not join private aviation.
