I've now started to receive teensy quantities of CLI-42 carts from the recycle chain. Initially I was excited until I started to attempt to flush them with normal procedures.
As we know the yellow is a feared monster to start with. As it turns out, when these carts are left to dry out and exposed for long periods....things happen.
What things? With the exception of LGY, GY and BK, the other colors are hard to flush out. Processes that would have a CLI-8 spanking white in no time cannot begin to remove the dried out ink. It just hangs in there.
As expected the worst culrpit is yellow....stubborn as hell. The others including PM which normally is an easy flush is also tough.
The first attempt was to use diluted LA Awesome as recommended by some as an aggressive flush agent. No dice.
The only thing that appears to work to some degree is something similar to what Hat used and that is dishwashing liquid. With this, you need to be careful as some contain hand conditioners etc. The other issue is that it is difficult to rinse out properly and this could be why Hat had some issues with his flushed carts. I reckon you need as much as 3 liters of flushing water to get the detergent out. Now you have to get it out properly or else the remaining chemicals will modify the surface tension properties of the incoming ink.
What is clearly evident is that when the CLI-42 ink dries....it becomes much more aggressive in holding on than previously thought and completely removing it can be difficult. Though the CLI-8 is called Chromalife, the CLI-42 Chromalife is a different animal altogether though the name is similar.
Before the ink dries... flushing is much easier however. ...but ink does dry in the sponge at some point no?... Will leaving some colored sponges in there be safe after a flush? I don't know as yet. The safest route is to used CLI-8 bodies for refilling if the CLI-42 bodies cannot be cleansed properly when they need a flush.
I will continue to try various chemicals to see what will work. These results are preliminary as the sample size of the recycled carts are very small so far.
