Star San Sanitizer

Star San Sanitizer

Please select from the following option(s) to see pricing and availability.

Star San is an acid based sanitizer that is quick, odorless, tasteless and safe for most materials except softer metals. Use of 1 oz per 5 gallons of water and a contact time of 1 minute makes Star San very economical and convenient.

As a high foamer, Star San's foaming action insures 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, and is perfectly safe and non-toxic, nor will it impart any flavors or odors. 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.

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 of the solution once diluted? I am storing the diluted solution in a 2 gallon food grade bucket with the lid on tight when not in use. Will also dip various tools in from time-to-time to sanitize.
Matt Telfer on Oct 13, 2021
BEST ANSWER: The best way to know is to check the pH before you use it. If the pH is below 3.5 it should work for you. If it is super cloudy or slimey feeling then probably you want to throw it out. One quick way is to taste it, and if your reflexes kick in and you immediately want to spit it out then it is good. If it tastes like a sour beer or candy then it isn't strong enough.
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.

Essential product and a great performer
I have used Star San products for years to sanitize beer lines and all brewing equipment. No rinse feature is a real time saver and the product does what it’s supposed to do. Sanitize!

Best easy way
I was super excited to get this product. It is easy to use goes a long way . 20 years ago things were different and harder and messy. With this I have a 5 gallon bucket full and did my beer bottles and wine bottles. Love it!

Great for more than just brewing beer!
I use this around the house and kitchen all the time. Be careful with household surfaces, test to make sure it doesn't damage or discolor.
