• What is mildew? What does mildew look like?
  + −

  Mildew is more than just an ugly stain; it's a living fungus that anchors itself to bathroom surfaces—and it won't go away until you kill it at its roots. Mildew is usually black but can appear pink, red or green. Highly humid areas have the most mildew growth.

• What are the most common locations for mildew to grow?
  + −

  Mildew often grows in bathrooms and other locations in the house because there is a combination of poor ventilation, moisture and food sources (i.e., body oil, soap scum, paint and oxygen). In the bathroom, mildew can grow anywhere: in grout, in shower tracking, on windowsills, on the ceiling and under the sink.

• Why does mildew grow in the caulk & grout in my shower and on the ceiling?
  + −

  Mildew grows in grout because it is a porous surface that can be constantly wet. Mildew is also often found on bathroom ceilings because of poor ventilation and a ready supply of food and moisture. In addition, mildew can grow behind caulk if its watertight seal has been broken. Unfortunately once mildew moves behind the caulk, it is hard to penetrate with a cleaner. If this is the case, you should get professional cleaning assistance.

• What can I do to prevent mildew from growing?
  + −

  Mildew needs moisture, a source of nutrition and the right temperature to grow. To prevent mildew from growing, you need to improve ventilation in your bathroom by installing a fan or opening a window. Plus, you can use Tilex® Mildew Root™ Penetrator & Remover as directed to attack mildew at its roots.
