Took the plunge and built a homemade mash tun last month. A little worried at first, I tested it for leaks and it didn't leak at all. Happy with my build, I put it away. A few days later I went back to place a few things in it that I had purchased. Upon opening the lid I noticed that the stainless steel clamps (purchased from lowes) on both ends of my mesh hose filter had completely rusted over. Has anyone else ran into this? I thought they weren't supposed to rust. Any suggestions for some replacement clamps?
