Digital BW, The Print

I am thinking about trying the PKN and LKN inks in a 7600.  I need to flush the lines, and 
still do have some cleaning fluid left in my MIS cleaning carts. I would like to buy more 
fluid in bulk rather than pay for the carts again. 

With respect to UC and UT inks:

Is the cleaning fluid just  "base" that you can buy from MIS, or is there something else 
important in there?

How about Jrano, you can buy that in bulk from Mediastreet.

thanks for any insight.
