This is a must have for any home brewer! No rinse, no worries, no contaminations!
Star San is an acid based sanitizer that is quick, odorless, tasteless, and safe for most materials except softer metals. As a high foamer, it’s foaming action ensures coverage and contact time in larger vessels and better penetration into nooks and crannys. Any foam that is left over in your carboy or keg will not harm your beer or you. If you plan on making some up for spray application, it is best to use distilled or RO water to maximize the life of the unused portion (minerals in tap water reduce the shelf life of Star San once in solution). If a lower foaming alternative is preferred, for bottling or multiple batches, check out Saniclean.
  • Use 1 oz per 5 gallons of water 
  • Contact time of 1 minute 
  • Completely safe and non-toxic
  • Will not impart any flavors or odors
Shipping Restricted: This product is only eligible for ground shipment within the contiguous 48 states.

Is it ok to use on stainless equipment?
john breithaupt on Mar 7, 2018
BEST ANSWER: Absolutely! That's what it's made for. You can sanitize stainless or plastic brewing equipment and its no rinse. Just make sure you dilute it correctly as per the instructions on the bottle. It does foam quite a bit so if you want the no for version use the five star SaniClean.
Is StarSan safe to touch with your hands while submerging your equipment? And with it being highly acidic does it speed up breakdown of plastic/rubber equipment (Swing top bottle gaskets etc.)?? Thanks.
Jeremy on Jul 19, 2020
BEST ANSWER: In terms of hand and skin health it is best to limit exposure of StarSan on your bareskin even when diluted. There should be no major problems with dunking your hands in the sanitizer or using scrub pads with starsan while barehanded. That said, in my personal experience, with continual daily exposure your skin can become very dry and cracked. Nothing a very robust hand lotion can't treat after a long day or weekend of brewing and cleaning.
What is the shelf life for this product? I bought a 16oz size about 6 years ago and after about 60 brews with it I'm only halfway through the bottle. It seems to still work same as it did on day-one, just wondering.
Robert Nissen on Jul 14, 2018
BEST ANSWER: It should last years. It is an acid based sanitizer. Long shelf life.

Good but foams of agitated
Works great as sanitizer. Just note if you shake say in a keg when sanitizing, it will get foaming. Then you need to add time to air draw. If not agitated it holds well with warm to cold water.

This stuff foams too much to be used on my bottle sanitizer. It is find for other stuff. I like that you do not have to rinse so keep buying it.
