After a peaceful "trouble free" summer with my pool (thank you TFP!), I'm getting ready to close this week. In cleaning up my stock of pool supplies in the garage, I see that I have 6 gallons of liquid chlorine leftover from this summer. Any chance at all that they will still be viable next summer? My garage is unheated, so there should be no problem of heat or direct sun light over the winter. I hate to just throw it away; any suggestions or uses for this left over LQ?
