Just went downstairs to get my Funnel which is stored in my Plastic Coleman Extreme Mash Tun. When I opened the lid, I was Horrified. In the bottom, after my last Brew session, I must not have cleaned well enough as I now have some Mold issues on the bottom of my Mash Tun. Needless to say, I am in the process of tearing it apart and cleaning. I want to soak the inside of the cooler and the Copper Lautering Manifold in a strong Bleach/Water Solution. Think an hour is to long for a Plastic Cooler to be subjected to that?
