How long can sn solution last?

[Soontocatch]

Well I prepared a solution to ctb but I basically got pulled away from it.I had to take care of something that I had forgotten about.So do I need to create a fresh solution of sn once again or can I use the one I had prepared.Its about a week old now

If I do have to create the solution again how do I dispose the current solution properly so that it doesn't harm anyone else
