To get rid of mold in the bathroom, locate and repair any water leaks in the room and ventilate the room to prevent the development of mold. Clean the room with a combination of chlorine bleach, water and detergent, or clean the room with vinegar and baking soda to remove the mold.
Ventilate the area by opening a window or turning on a fan after bathing, and dry the sink, bath and shower with a towel after each use. To kill mold that is present in the room, clean walls, showers and other fixtures by spraying the area with undiluted white vinegar. Scrub each area with a brush, and rinse with clean water.
To remove mold on grout, apply a paste of three parts baking soda and one part water to the grout. Spray undiluted white vinegar onto the baking soda paste, and scrub the grout with a firm brush. Rinse with clean water.
If the mold persists, spray the affected areas with undiluted hydrogen peroxide, and rinse with clean water after three minutes. Do not mix vinegar and hydrogen peroxide, as the combination can be life-threatening. Another option is to clean the room with a solution of three parts water and one part bleach. Spray the bleach solution onto the affected areas, scrub with a clean cloth or brush, and rinse with cool water.
