Clorox bleach. You can put it on with a small paint brush, "my preference" or spray it on. Just make sure there is ventilation in the room and get out fast because it is not good to inhale it. Wearing a mask is a good idea. Just shut the door for a while then go back and rinse with cold water. It's the only thing I have found that really works well.Clorox has come up with a new type that doesn't smell as strong but I haven't tried it yet. Opening a window and the shower curtain after you shower will help slow the mold growth. If you don't have a window then turn on your exhaust fan and let it run for about 45 minutes after showering.
