How to get rid of that sewage smell?

Haha with baited breath, I'm sure.

The smell went away shortly after posting this. Still comes back intermittently (but not as frequently as last time - maybe because it's been colder outside?). Called our landlord and will be having a plumber come out since our methods have not worked and since it's a rental property I don't feel comfortable doing more than what we've already done.
