toilet and its vicinity
I did not have this problem when I lived alone without guests over. Now, I have a messy husband using the toilet everyday and children guests from time to time. No matter how i clean the toilet and its vicinity (I clean the entire bowl in the out, as well as the vinyl floor), the urine smell always is present. I don't use any cleaner though, because I am allergic to chemicals. I can use vinegar, baking soda, or that sort if they help.
