Five Star says to sanitize before storage, it leaves your 'stuff' in an acid state.

A Email from Charlie Talley(Five Star Chemical Founder) from 2003

Hi :

When I ran the bacteria tests 30 years ago I always had kill within 30
seconds. What EPA will not let tell people is that I also ran tests where
items like milk, cola, wine, beer, and other food items were in the
bacterial test as well. These items when introduced into a test will
normally cause the test to fail. This is exactly what happens when iodine
or chlorine are tested. The Star San passed! It not only passed it had
99.99999 (7 log reduction) in one minute! That is why I tell people it is a
stone killer

As for the residual yes it will keep organisms from growing as long as it
doesn't come into contact with moisture for about one week. At least that
is what my non-EPA tests have proven.


Keep in mind that Star San is an acid so do not have soft metal like copper
exposed to it for long periods of time (more then the 2 minute contact
time).

Charlie

Interesting, they don't mention what you highlighted in blue in recent interviews.  I took a look at their spec sheet online it says

"Cleaning with STAR SAN HB on a daily basis will leave equipment in an acid condition that will eliminate water spotting, mineral build-up, and corrosion.

Always sanitize equipment just prior to start up with a suitable sanitizer as required by local public health regulations.


I always do both

So, an 11 year old email about a 30 year old set of tests....

I'm not going to doubt the accuracy or sincerity of what Charlie wrote. I'm certain he'd still stand by those words, but he'd likely modify it with what've become best practices among his customers.

By comparison, Pro brewers often use a sanitizer that's more powerful than starsan. Peracetic Acid (aka peroxyacetic or PAA) is stabilized hydrogen peroxide in a modified vinegar base. A little on the skin will feel like needles and turn it chalky for a while.

Breweries with good lab programs swab out all of their dormant equipment periodically. Numerous reports from these brewers show that after 48 hours, platable levels of contamination exist inside sealed fermenters and bright tanks. So, the industry standard for using dormant tanks after sanitizing is 12 to 20 hours max.

PAA is also used as a bleach substitute, but it doesn't really have a place in homebrewing.
