<human>: Summarize the given text in a few sentences.

I recently got a new roommate, and we get along quite well except for the fact that she doesn't clean. It was ok in the beginning, but now I'm starting to get annoyed this. I've told her numerous times to do her fair share of the work, and clean up after her own mess. She said she "doesn't know how to clean up" because she was raised with her grandparents cleaning up after her. One time, she asked me to help her to clean her bathroom, because she doesn't know how to. 

I'm not a complete neat freak, but I don't want unclean dishes in the sink, garbage pilling up, and dirt on the floor all the time. I've talked to her about this situation before, and all she responds is:  "I don't know how to." How do I get my roommate to clean up after herself, and not make the apartment look like a mess?
