I've not had to recycle my EP cuvettes yet, but I have several hundred of them
lying around in case times get tough!  I noted in a product review in Nature
347, page 310 a year or two back that an ABI robotic PCR machine uses a dilute
nitric acid wash to remove DNA from its single PCR plate (I forget whether it
was aluminium or not, but I suspect so).  I reckon that if nitric acid can
clean a plate sufficiently that there is no carry-over of DNA between the PCR
reactions then it ought to be effective at cleansing EP cuvettes.  Perhaps it
is worth a go - let me know if it works!
