Hve you done something as simple as asking them to do it? Not nagging that they haven't. I suggest a good old fashioned rota on the wall, maybe even complete with stars! If everybody eats, everybody should contribute to the cooking first & clearing after. You may need to lead them in a bit gently by reminding each one that tonight is their night. Then after a week, leave them to it.
It was serving dinner in cereal bowls - the only crockery left clean - that made my lot realise I was serious.
Good luck.
