When cooking dinner, you probably turn on the stove without even considering the nasty germs that may be lurking there. But did you know that these seemingly innocuous knobs may be one of the dirtiest places in your kitchen? It's true: Around one-third of stove knobs are filled with yeast and mold, according to a 2011 study. To banish the germs, remove your stove knobs and soak them in a solution of white vinegar and water to disinfect. If the stove knobs cannot be removed, simply spray the knobs with the natural cleanser and wipe down after 30 seconds to restore them to pristine condition.
