I’ve not used Star San before. In the past I’ve had a powder cleaner and dumped it after each use. But lately I’ve been reading people fill a squirt bottle of star San and it lasts forever. Here are two questions.
If I mix up a 5gal recipe of star San can I keep it sealed in a Home Depot bucket? I’ll use it to sanitize my next big mouth for secondary this weekend, then I’ll save it and sanitize my bottles and equipment on brewing day.
What can you actually sanitize with just a spray bottle? Doesn’t seem like you can be confident your equipment is truly clean.
