One of the most persistent problems plaguing homeowners is mildew – particularly in high-humidity areas, such as the bathroom. If you think it’s a problem for you, then you should walk a mile in my shoes as a Certified Master Rug Cleaner, who routinely deals with mildew and fungus growth in water-damaged homes.

In order to rid yourself of mildew, you first need to know about its origin. Mildew spores are in the air we breathe and need only proper conditions before becoming active growths. So, just what are those conditions?

Basically, there are five:

  1. A natural food source: Jute rug backings or soap scum on shower walls.
  2. High humidity: Wet rugs and carpets for me, humid living space for you.
  3. Relative darkness: Again, rug backings, but also rooms with privacy and blackout shades.
  4. Stale air: Mildew hates fresh air, not only because of its drying effect, but also because it contains gases that may prevent growth entirely.
  5. Warm temperatures: Ideally, 75 degrees to 78 degrees Fahrenheit.

Now that we know how to grow mildew, just how do we prevent it? The answer is simple: Eliminate the conditions required for growth. The catch, though, is that your entire family will require retraining – no simple task, as conscientious moms have discovered. What’s involved in your retraining program?

First, regular cleaning with “soft scrub” products – use chlorinated, abrasive cleansers in desperate situations only. Regular cleaning ensures mildew has no food for growth.

Second, reduce humidity rapidly by using your bathroom exhaust fan while showering and for 15 to 20 minutes after completion. This is particularly important for teenagers who take marathon shower sessions. It’s also a great idea to provide a window squeegee in the shower to wipe down the walls or quickly wipe walls relatively dry with a used towel.

Third, let the sun shine. Open blinds and roll up shades as soon as possible. Sunlight provides warmth and ultraviolet rays to speed drying and destroy mildew.

In severe situations, such as damp basements, the ultimate solution may be the purchase of a dehumidifier for operating during humid seasons of the year.
