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.
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.

It does the trick. Never understood why it's toxic and you can leave it on food items but it keeps stuff sanitized.
