If you have mildew or mold in your closets or cupboards in your bathroom have a look at the following tips to fight it clean:
Try to increase the air circulation in cupboards and closets that are prone to mildew problems. The circulating air will help deal with the dampness that mildew thrives on. You could consider replacing doors with louvered ones. Try cutting the bottom of the doors a few centimeters short so air circulates better.
Keep items that tend to suffer from mildew, such as shoes and suitcases, on racks or shelves that have holes in them, like wire shelving. That way air will be able to circulate around them preventing mildew.
To Keep mildew away from damp, musty areas, by placing a charcoal briquette in each corner of closet, or wherever mildew appears. The charcoal will absorb the moisture that mildew needs to survive.
Also to eliminate mildew, dust and odors, wipe down areas with vinegar-soaked clean cloth.
