I'm flushing old carts TODAY - Any ideas on what I could use as an "non hazardous" Algae killer pre treatment?
Fill with vinegar first, or something like that?
I think I posted on another post Leo - Various old carts I've collected that I know nothing about - age/ink contents, but it's a bunch of free Canon carts that I can use new ink in.
I'm not sure if you can prevent bacteria from growing in your cartridges or in your head. I had a problem with certain inks that grew bacteria in the cartridges and in the head between the inlet screen and the jet ports. Here is a link to my previous post: http://www.nifty-stuff.com/forum/viewtopic.php?pid=16189#p16189
To keep bacteria from forming in my ink I add a little alcohol to my ink before refilling cartridges. I think the alcohol finally solved the bacteria problem, I haven't had problems since I switched ink vendors and adding alcohol to my bulk inks.
Before adding alcohol to my bulk inks I had bacterial goop growing in almost all my inks except pigmented black.
If you have algae and bacteria growing your ink, then the problem is your supplier/manufacturer. Good quality ink contains enough preservatives and chelators preventing bacteria and algae from growing for several years. The minimal autopreservative concentration of alcohol is about 20 %, that's the reason that any wine/liquor with a concentration above 18 % can be kept for decades without spoiling. Why normal wine can not contain more alcohol than 15-16 %, because the yeast inside producing the alcohol from the sugars will be killed off when the alcohol concentration is increasing over time.
