Sometime I probably will throw it out and make a new 5-gal just due to paranoia, but 1 year on 1 oz (?) of starsan concentrate makes for a pretty economical sanitizer.
Just an FYI. I had a "hiking/work-out" shirt from LL Bean, made from some space age fiber, and I spilled concentrated StarSan on it, and it lightened the color and made a permanent mark. So, if you are not already, wear cotton while brewing.
