salt? some people don't use salt in their cooking and that quickly speeds up bad things. Long time ago working student summer construction jobs in Siberia we had "perpetual tea" going for several months - several electric tea kettles were always on at close to boiling, and we were putting into them, without any selection, whatever green stuff was growing higher than 2 inches - ie. above the moss - in the pine forest around. And I don't remember pulling old stuff ever out, only adding new one into the kettles.
