I understand the importance of cleaning and I take it very seriously, but then again, if it is not necessary to use what little Craftclean I have left, I'd rather not. I had used my auto siphon for my mead and cleaned it thoroughly after. Then I put it somewhere clean and never touched it again. My question is: I am about to take a reading of my beer to check whether or not it is ready for bottling - is it necessary to clean my auto siphon once again even though it had already been cleaned a few days ago?
