In my old lab we would always reuse electroporation cuvettes.  Washing was done in 
water, distilled water, and finally 70% ethanol.  I would sterilize prior to re-use 
by UV irradiation.  Note that cuvettes cannot be reused indefinitely -- eventually 
they will arc and that will be the end of that.
