Flatmates are disgusting

I share a flat with 3 other people (was four but he moved out…no surprise). Two of them invite friends over just about every night but never clean up. There’s food, spilt drink, bottles, and muck left all over the cooker and sink. Dishes everywhere…used pans left on the hob for DAYS as well.

This has been going on for weeks. A few times myself and another flatmate cleaned up ourselves, despite it not being our mess, and asked the others to keep the kitchen clean but they just haven’t taken it on board. They’re both international students and have said back home they had maids cleaning up after them.

I feel like I’m talking to a brick wall when asking them to clean. It’s gotten to a point where all I can eat is cereal because I don’t want to be in the kitchen to cook. What do I do? 😭
