How can I get rid of the smell and black mold only in my toilet bowl? Do I need a professional?
My upstairs toilet that is used about once a day grows black mold very quickly. I am cleaning it with Clorox about once a week. I checked and there is no mold in the tank. It has just this week started emitting a foul almost sewer-like odor. The smell is coming from the water in the bowl and not the water in the tank. All of the other toilets in my house are smelling fine and only the basement toilet gets mold occasionally from lack of use.
