DEPC CAN be used to treat some solutions, just not those made with
amine-containing compounds, like TRIS.  However, LiCl, NaOAc solutions and
the like can be DEPC treated, although such precautions are often not
needed if care is taken, even for water.  As for the specific question
regarding treatment of EtOH-- just use an unopened bottle and use
DEPC-treated (or other RNAse free source) water to make the 70%.
