Since these guys don't ship to Canada anymore, I might have to go the DIY route. Ultrasonic jewellery cleaners should do a similar job of cleaning, on the exterior at least, and cost only $25. I imagine that if I ran a low voltage current through the injector while its in the bath, the inside should clear up as well. Now I just need some cheap injectors to see if the DIY method would work.
