I bought a kegerator from a buddy of mine almost a year ago. With every batch I have had since then (probably 6 total) I have noticed little black floaties that show up in the beer. I have clean and sanitized the hell out of the keg and have no idea where these could be coming from. There are usually 2-3 per glass of beer poured (some really small and some about the size of an aunt). I have read that since I have a converted soda keg they could be left over pieces of cola but I don't think there could still be any left after six batches. Any ideas on what to do? I just kegged a summer ale so the floaties are very noticeable since the beer is so light. There is some stuff in the lines of the CO2 tank to the keg but he said I didn't need to worry about those since they would never affect the beer.
