    Bleach works well. Roll up a portion of paper towel and apply a solution of bleach and water and let it sit for 15-30 minutes. It should remove the mildew. Rinse well and then follow up once a week or so by spraying 1:1 ratio of white vinegar and water to keep the area disinfected so mildew does not form again.

    Pull up the old caulking, clean the area well, then put new caulking down.

    Make sure the the caulk hasn't come loose from the wall and started to mildew behind it. Then, apply a bleach solution directly to the mold or mildew by spraying. Then attack with the brush as normal. This solution is best used on mold or mildew present in bathrooms, kitchens, and other household rooms with tiles or non-porous surfaces. Bleach is very effective at killing mold and mold spores.
