Removal of CsCl from CsCl-EtBr gradient preps

I am posting to inquire if anyone can give me a easy way of getting rid of
the CsCl remaining in EtBr-extracted CsCl chromosomal preps?  I have 
routinely used Amicon Centricons for plasmid preps, but believe these will 
get clogged if I use them for chromosomal preps.  I've tried the method in 
the new Maniatis (add 3 vol d.H20 + 2 vol EtOH) but that didn't work.  Is 
there any other method besides dialysis?

Thanks in advance,
