Hey mickster and
to TR.
I keep mine for a few weeks in a Brute, kind of making it up, using most of it, adding some more fresh and then starting over. I have found that if I don't empty it totally and rinse it out after 6 weeks or so the sides of the container start to get gunky looking. This may not be harmful but, like Jon said, why chance it?
Where are you from in NC?
