I am guessing you don't do much paint stripping or rebuilding old bad looking models. Myself I have left a body in the pond for six months, as a matter of fact I just pulled out a Maverick Jo-han body and interior, Cleaned it in the water and now it is sitting in primer. I just keep it in the plastic container on the floor under my desk, and when I want to soak a body I do so. I think it is a chemical so I don't think it is a good idea to pour do the drain put it back into the jug it came in. If you want it gone take to a place that takes old paint and oils, a chemical recycling.
