How to Get Rid of Mold in a Toilet Tank With Vinegar

Mold and mildew fungus thrives in the moist environment of a toilet tank. With regular cleaning, mold growth is easily prevented or removed. But when the toilet tank has been forgotten for awhile, you might be appalled to discover mold spores inside once you finally remove the lid. Although bleach and stronger cleaning products successfully kill and remove mold stains, they also introduce harsh chemicals into the water and the environment. Vinegar is a natural mold killer that cleans and freshens the toilet tank. You can get and keep a clean toilet with regular use of white vinegar.
