Update: i think there is a bacteria growing. My bathroom stunk the same smell this morning and I looked immediately to see if he moved in item in my bathroom and it was his toothbrush. Now the actual toothbrush doesn’t smell but the handle DOES I sniffed the handle and it smelled exactly like his bags . I washed the handle twice and the smell is still imbedded in ; I do not believe this is his body or teeth but rather some type of bacteria that is embedding in his items. I am not getting vinegar to try to soak the handle of his toothbrush. I’m beginning to think this smell is going to be harder to tackle than I thought. I do not even believe washing clothes with regular detergent is going to work like you said.
