I am newer to brewing, I just bought Star San. I was using an Iodine based sanitizer previously. I got away from the Iodine for a few reasons. But its irrelevant. Someone on this blog said Star san is the best for removing labels. I have the bottles soaking in the 1 ounce to 5 gallon dilution. I hope the labels come off. I also hear that Star San has a good shelf life. If I take the Star san and strain the label gook out, Can I use it to then re sanitize the bottles before I bottle? And whats this whole foam joke about? I see a little when I sanitize my hydrometer and all, Is it really that bad on the larger scale??
