I try to keep up on cleaning my water cooler. Recently i was tasting and smelly a musty oder in my water, I kno the dangers of mold. I had been using a DIY cleaning method I found online. Still i was smelling this oder and specks of white film where despencing out. So after finding out more hidden dangers I did more exploring, Put together my own solution to my problem. Today Im happy w/my results. My water has never been clearer and better tasting, and I also used this method on my coffee maker.
