Wizard Preps: DNA Doesn't Freeze

I often notice that the DNA solution does freeze but thaws more quickly than
I would expect. I suspect that there is quite a bit of salt coming through in   
the wash. I find that doing an ethanol ppt followed by 70% wash solves the      problem. I have to do this anyway to get the DNA to the appropriate
concentration for what I want to do, so it's not too much hassle for me.
