Use 25% to 30% beach with water to kill the fungus. Allowing the shower area to dry after each use will lessen the times you need to do this. Using the vent fan will help also. I leave the shower door or curtain open after each use to allow air to circulate to dry it faster. Make sure the room is well ventilated by opening a window and using a box fan or sort to get the fumes out of the bathroom will cleaning. You may need to steep out of the room a few times if you are bothered by this.
