Go Green - Flexo Ink Cleaner

I came across this site that features the top selling flexo ink cleaners. This is actually the first time I heard about the Flexo ink cleaner. I've been with Purchasing for a long time now, and I am somehow familiar with the different types of printing - there's offset printing, riso printing, mimeo printing and a lot more. But this is the first time I heard about how these printing machines are cleaned. I always thought the alcohol and cloth are the only cleaning supplies printers use to clean and maintain their machines. Apparently, in the US there are companies selling different flexo ink cleaners. These companies not just sell ink but they also promotes having a green environment. The chemical cleaners they offer are environment friendly, nice is it not? It is really nice to know that the number of people becoming more aware and helps promoting conservation of the environment are increasing. Hopefully, all these efforts are not too late.
