I did have a problem with storing EIS in plastic jugs used for vending DW. The silver precipitated out after several weeks. Since then I have used a two-stage storage method.
The first stage is for stabilization and long-term bulk volume without H2O2. The vessel is a 1-gallon tinted glass empty wine jug. These are sold at any supermarket that sells wine. The cost (if full) is less than the cost of a Maple Leaf bullion coin used as a cathode. I think it is a good investment. The second stage storage receives EIS that has been refreshed by re-electrolysing and nanopulverizing, to coin a term, with hydrogen peroxide. I never let EIS treated with h2o2 back into the first-stage stock storage vessel or the electrolysis vessel, lest h2o2 interfere with re-electrolysis. The second stage storage vessel can be a smaller, less expensive glass wine bottle. Granted, it takes extra time to initiate this two-stage process. But time is saved later by the rapidity of re-electrolysis using stabilized stock EIS as its own 'starter' instead of beginning with pure DW each time.
