Mix equal parts baking soda and white vinegar together in a spray bottle and spray onto the stained area. Let sit for five minutes, then flush the toilet. This method works well because the baking soda neutralizes the acidity of the vinegar, making it easier for the toilet bowl to clean itself.


Mold is a fungal organism that grows on moist surfaces such as walls, ceilings, floors, pipes, and other porous materials.

Mineral Deposit

Fungus is a type of microorganism that grows in soil, decaying plant material, and other organic matter. Fungi are not plants; instead, they belong to the kingdom Protista or protozoa. They are eukaryotic cells, meaning they have a nucleus and organelles such as mitochondria and chloroplasts. Fungi reproduce sexually or asexually. Asexual reproduction occurs by spores, which are produced in special structures called conidiophores. Spores are carried by wind, rain, insects, birds, and animals. Sexual reproduction produces two types of spores: haploid and diploid. Haploid spores are only half the normal size and produce gametangia, which develop into zygotes. Diploid spores are larger and produce meiosis, which results in four nuclei.
