Hi, I’ve got a couple of questions. Firstly, I’ve got the granulated type of no rinse sanitiser which you dissolve in warm water. Thing is whenever I finish sanitising there are granules left behind that haven’t dissolved which I end up having to rinse away (defeating the object of no-rinse). Does it matter if I leave these granules in my FV or keg and effectively in the beer. Alternatively, any suggestions for getting them all dissolve? Secondly, how do you ensure that all traces of water are out of your beer line after cleaning. Just got a party tap assembly out of storage and there’s a little black mark of mould in it I’m guessing where there was some water left behind. Part two of this is whether that line is now dead or whether I can still clean it? If so how?
