Ugh tell me about it. I do a thorough clean, including floors, once a month, and weekly cleanings of the toilet bowl and sink. Early last week, a bottle of cleaner spilled, and has since gathered every bit of hair and lint it could. My cats like to sleep on the bathroom floor too, so their fur also got caught. AND, I bathed and gave my black dog a haircut yesterday, so of course that shit got everywhere. So yeah, the floor is not new (clean now, today was planned for bathroom cleaning anyway, hence doing dog stuff yesterday so as not to sooo freshly cleaned bathroom), but the toilet bowl/seat had been cleaned a few days ago. He has explosive diarrhea daily, from what I can tell.
