So, I purchased the MM cleaning kit, and maybe I just missed it in the directions, but what goes in the bucket with the coupler and all in it? Do I leave it empty so the solvent that went through the lines fills it eventually, or do I fill the bucket with a solvent mix, or just warm water? This is important. My second keg is slowly starting to taste like crap and randomly pouring strange and since my handle is getting hard to pull I think it's because it really needs to be cleaned. Which equals-no keg for this guy! Please help.
