In several shared living environments with all adults I have noticed a pattern of differing hygiene standards. I would find certain levels of uncleanliness in bathroom or kitchen unappealing, whereas others did not seem to have a problem with it. When living alone, I just clean when I feel the need. With other people around I can still do that, but then it will be me who cleans almost every single time.
Other tenants would then just say that they don't have an issue with that, that they still feel comfortable and my standards for cleaning are annoying. Or that they simply don't see the dirt. Some might be benign ignorance, but often I also feel laziness and entitlement of not having to clean.
On some occasions I have tried to endure the dirt and see whether other people would start cleaning eventually. This just does not work for me because I have to live in a dirty condo for weeks before anything starts to happen with the people I have in mind. This is not a winning strategy.
Then I have tried to set up a cleaning schedule. The problem there is that somebody might “clean the bath” but they just do the bare minimum and it still needs cleaning from my perspective. Then I try to establish a norm for bath cleaning, but I can feel how certain people just don't care.
Just letting it be without a formal plan and occasional assigning cleaning to people also does not work that well. This way I often think that it is easier to just do it myself than bringing another person to do that. Of course, this is not a long-term strategy either. And sometimes I would say things like “you have left a lot of dishes on the counter” and get confronted with this one time where I did not put mine into the dishwasher. Because I wasn't perfect, they don't accept the criticism.
In the end I can either just do all the cleaning for several people, or do a lot of even more laborious nagging and pushing to get people to do their share. Both suck away energy, and I would like to make them do their share. Is there a way, or is a shared condo just impossible with such flatmates?
