STAR SAN is a high foaming, acid anionic, no-rinse sanitizer that is effective and easy to use.



Dilute in cool to warm water (50°F to 120°F) at a rate of 1 oz per 5 US gallons (6 mL per 3.8 L jug). Made with tap water, Star San will remain effective up to several weeks. Made with distilled water, Star San will last more than 3 months.

  • Made from food-grade phosphoric acid, STAR SAN is safe for people and the environment.
  • Star San is self-foaming, which helps it to penetrate cracks and crevices.
  • Odorless and flavorless, no need to worry about tainting your beer or wine.
  • Does not require rinsing when used at the recommended dilution.
  • Use only 6.5 mL Star San per 4 L of water and just 1 to 2 minutes of contact time.
  • Used as a soaking solution, it can also be applied by hand (wear gloves) or with a spray bottle.
  • Reusable: a solution of Star San will remain effective for up to three to four weeks in a sealed container; it is effective as long as the pH is 3 or lower.
  • It is safe for use on all surfaces, but use caution since it is an acid; contact with soft metals, rubber, and plastic should be kept to a minimum. Star San is environmentally friendly, biodegradable, and will not harm septic systems.
