When it comes to mold, some people think that bleach will do the job. This is simply not true. Bleach neutralizes quickly, so it doesn't have adequate time to completely wipe out the organisms. By the time the smell is gone, so is the ability to kill microbes. And ironically, as it neutralizes, bleach leaves behind its main ingredient.. water. Which gives the microbes even more of what they need to survive. The Anabec products work on a microscopic level to remove unwanted microbes from surfaces, and helps prevent them from returning.
