Hi everyone. A quick question. How do I dispose of an old bleach solution? I suspect pouring it down the drain or on the ground is not a good idea. I made a strong bleach solution several months ago to do some heavy cleaning (long story), and the remainder has just been sitting in a bottle. I need to make a fresh batch to do some more heavy-duty cleaning, and obviously I want to use the same spray bottle. So I need to get rid of the old batch, because I heard the stuff loses its strength after a while. What do I do? Thanks.
