<human>: Give me the gist of the text in a nutshell

So I'm currently living in a 6 person apartment with one friend and 4 random people I haven't met before. Living with them has been hell and I'm planning on moving out at the end of the semester but in the mean time I need to find a way to live with them for the next 11 weeks,

At the begging of the semester one of them asked if they could borrow my Pyrex baking pan and trying to be nice I said sure. This was before I knew they were pigs. Four days after my roomate used it he finally washed it but did a terrible job so I ended up re-washing it myself making a note to myself not to let them use my stuff again.

That was 3 weeks ago, but recently (starting 1 week ago) they have begun to start using my pots and pans and sometimes plates/bowls without asking. I'm pretty laid back and honestly I don't really care that they are not asking me, the problem is whenever they use a pot or pan, they do the worst job at cleaning it and one time they even put away a pot that they didn't even try to clean!

I was hoping this would be a one time thing but it has been happening consistently and I have no idea how to address it. I want to tell them that I don't want them using my shit anymore but I don't want to sound like a dick when I do it. Any suggestions?
<bot>: Roomates keep using my stuff and returning it dirty, don't know how to nicely tell them to stop using it.
