    Thanks for the updated info. I increased the amount of ammonia a couple of months ago when I had a stubborn printhead clog. I left the printhead in the solution for three days, not on top of a drenched paper towel, and rinsed the printhead under water every day. My dye based clog improved but then I developed a pigment black ink issue. I think leaving it in the cleaning solution that long caused the new malfunction. One new printhead later and everything's perfect again.

    Have a full set of carts ready for unclogging solution when it happens again. I also have more glycerin than I'll ever need in a lifetime! Any ideas on what else to use it for?

    If you make the mistake of purging your cartridge before filling it with cleaning solution, you will discover that you cannot tell if you have succeeded in unclogging your print head (because cleaning solution is like invisible ink) unless you constantly swap your cleaning cartridge with a regular cartridge, thus wasting a lot of ink.

    You can use the glycerin as hand cream, make facial cream, use it as mild laxative (very sweet), but it will preserve for centuries to come without deteriorating. Pure glycerin is completely safe to drink, but will make you to the toilet more frequently.

    I would like to know what ink everybody is using to cause so many print head problems.
    I dont purge or cleanout my cartridges at all and never have.
    However if I do an sample ink test then I wash out the spare cartridge that I have as I never mix any 3rd party inks together..

    Quick question... define "concentrated ammonia" ... what concentration are you using?

    25-30 % ammonia: this is concentrated ammonia. If you use household concentration, increase accordingly.

    Very good clarification. I assume the same is true for isopropanol alcohol. Example: In our bathroom the container says "70% isopropanol alcohol", so I figure the same is true that I also need to increase the alcohol accordingly?

    Glad I checked..

    Thanks for that information, obviously helps enormously...

    As FYI for those following this... the standard household ammonia in the UK is 9% w/w (weight for weight )
