I've used this method in the past, but did get contamination.  I started
rinsing the cuvettes in HCl (either 0.1M or 0.5M, can't remember off-hand),
and then washing with deionised water.  Store the cuvettes in ethanol until
you need to use them and there should be no problems.  Using this method I  
reused cuvettes quite literally until they fell apart, and my transformations 
were always okay!
