I have a roommate who is a really nice person but they are super gross, they never wash our dishes properly (they just run them under water, never use soap or scrub them) and their room is absolutely disgusting; filled with rotting food, months old cat litter, etcetera. Every time they open their door this smell fills the apartment that is like a mix of piss/shit/fermentation/rotting, it's at a point where standing 8 feet from their door I can smell it through the door, when they open the door it's worse.. I've asked them to clean their room before but I really wish they could consistently remove whatever is creating that smell, without me having to ask them. I'm dreading this conversation because I am afraid I will rage, but how would you ask them to consistently clean up after themselves? Like I don't care if their room is gross, but like it can't spill into the rest of the apartment...
