Star San Sanitizer FAQ
Is Star San a cleaner or a sanitizer?
Star San is strictly a sanitizer. It does not remove visible grime or organic material. Always clean your equipment first using a proper cleaner—then sanitize. Need a reliable cleaner? See our recommendation below.
How long does Star San take to sanitize?
Star San is fast-acting—surfaces are sanitized in just 1–2 minutes. You can apply it by spraying, soaking, or swirling the solution to ensure full coverage.
Do I really not need to rinse it off?
That’s right! If mixed to the recommended dilution (1 oz per 5 gallons of water), Star San is a true no-rinse sanitizer. It leaves behind no taste, odor, or residue when used properly.
Is it normal for Star San to foam?
Yes! The foam is a feature, not a flaw. It helps the solution cling to surfaces and coat equipment effectively. Foam is safe and can remain on equipment when you start transferring wort or must.
Can I reuse Star San solution?
Absolutely. If stored in a sealed container and your water is low in minerals, Star San solution can remain effective for up to 3 weeks. Check with a pH strip—if the pH is below 3.0, it's still good to go.
