What is mildew?

It is the bane of shower curtains everywhere, a disgusting creeping mess that thrives in warmth and humidity, which causes plenty of damage to the material on which it grows.  It is a substance so pesky that Krusty the Clown broke off a dinner with Bart Simpson to scrub it away from his bathroom.  This resilient growth is known as mildew, a black or white filmy residue left behind when mold invades your home or workplace.  Mildew is always a by-product of mold infestation, but not all mold will leave mildew behind.  The particular molds that are responsible for mildew formation are the kinds that enjoy moisture and balmy temperatures, and commonly strike during the summer, when the humid weather makes for an ideal habitat for them to flourish.  This is especially true of closed houses, which help to maintain these perfect mildew breeding conditions, due to the lack of air circulation.  Mildew forms quickly in poorly lit areas, as well.

   

 

  

Mildew develops on a considerable variety of surfaces and materials, which include paper, leather, wood and various types of cloth, such as cotton, linen and silk.  Synthetic fibers, however, like nylon and polyester, resist mildew, not being made of the organic elements that mold can and will digest.  As the mildew spreads on the affected area, it eventually causes the disintegration of the material, as it slowly gets damaged by being eaten away.  Mildew leaves a musty odor behind and discolors the objects that it does not outright destroy.

Dealing with mildew is a multiple-step process that begins with keeping clean any place where mildew could strike.  This includes basement areas, drawers and other locations that are susceptible to the accumulation of dirt and moisture.  A little dirt may be all the food that mildew needs to start growing once the proper environmental conditions have been established.  The next step is to control dampness, as sufficient moisture is needed for mildew to begin cultivating.  Moisture buildup in a particular area means that repairs may have to be made, or that the existing insulation is not enough to stave off outside moisture.  One may also wish to check the house drainage system to make sure that water has adequate exit points from the house interior.  For those who have to deal with crawl spaces beneath their houses, it would be prudent to pick up some moisture-barrier material and spread a layer of it over the soil – plastic film or roofing paper work fine. 

Make sure your home gets sufficient air circulation, which is integral to keeping moisture from collecting in parts of your house.  Good ventilation carries dampness out of your house and into the atmosphere.  If the wind isn’t enough to do the trick, you can always use electric fans, set in a position to blast air from the house.  Certain chemicals, like silica gel, are also good for absorbing moisture, though they may be a bit harder to get your hands on.  A little vigilance goes a long way in keeping mildew out of your life and property.
