Weird question, when I'm not brewing I store my buckets inside of each other and inside if my mash tun(10 gal round HD cooler) all my hoses and tools are in the buckets as well. I don't really clean my tun after use, I just rinse it and get most of the grain off, my question is do I need to be worried about a Lacto infection on my equipment from any grain remnants in my tun, or do I need to RDWHAHB?
