the starting fluid that comes in a spray can and says '50% ether' most definately contains diethyl ether. I kinda like to light a little fire and then spray some at it and watch it make a small little explosion in the open air. But I'm just weird that way.
I would say spray that out, wash it with water, then distill it, and dry it. That'd be about the best you could do.
Edit:Actually, I had a thought. What about dumping in some CaO and then distilling? If the other drying agents aren't hygroscopic enough to get the water out, will it not react with the CaO?
