Out of all the factors that go into making a good homebrew, sanitation is the most important\u2014infection will ruin a batch of otherwise well-made beer.\n\n\n\nThe most famous no-rinse sanitizer on the market for brewers is Star San. It isn\u2019t notably expensive, but with all the sanitizing a brewer has to do\u2014especially if they\u2019re brewing often\u2014the cost (and the labor) can start to add up.\n\n\n\nThe most common question regarding Star San is whether or not it can be reused once we\u2019ve diluted it.\n\n\n\nDiluted Star San can be reused multiple times providing it has a pH of 3.5 or less. Contrary to popular belief, clearness of the fluid is not necessarily a dependable indicator of usability. To gauge Star San\u2019s pH, pH test strips can be used. At a pH over 3.5, the Star San should be discarded.\n\n\n\nWell that's the scientific answer, but there\u2019s more to know about using\/reusing Star San, and I also want to touch on a point that confuses a lot of people new to homebrewing\u2014the difference between cleaning and sanitizing your equipment\u2014because Star San sanitizes. \n\n\n\nIt doesn\u2019t clean.\n\n\n\nKeep reading, because I\u2019ve got the answer to these questions and others!\n\n\n\n\n\n\n\nHow many times can you reuse Star San?\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n Plan your next Beer Creation?
