So my kegerator is done and I'm about to rack my beer into the keg but I have a quick question. I just got this keg and it has been cleaned and all o-rings are new. I know its good to completely disassemble the keg and sanitize the posts and all the other little parts after every few batches. But for this first batch is it alright to just put starsan in there and live it together, or should I remove the posts, tubes, and all other little parts? Thanks
