Just rinsing with water is insufficient provided you are using 
electroporation to clone. Residual DNA will appear in subsequent 
electroporations. Treat the cuvettes with 30% HNO3 for 1 hr after rinsing 
with water. Then rinse with water again and fill with 95% EtOH. I just 
let it dry down, but have also dried under vacuum after 24 hrs.
