How to Remove Mildew from a Mailbox Post

Mildew grows on surfaces that are consistently damp or in warm, humid climates. The mailbox post in your yard is exposed to inclement weather and, as it gets dirty, becomes a prime location for mildew to grow. It's important to remove the mildew spores early so they don't spread to the inside of your mailbox. While regular cleaning and maintenance prevents mildew development you can remove the stains and accompanying odor with supplies found around the home.
