We have discussed (on the list) the best way to keep an InkJet working (unclogged) is to use it... OK... Seems one of my printers seldom uses the Color cartridge. (OK, We forget to use color...) After it clogs, and running through the HP software cleaning (including excessive mode) what is the solvent of choice to un-stop the cartridge? I've been using alcohol, and it works about 50% of the time... (OK, busted... NOT the first time I did this...) Anybody use anything else... This comes under the heading, "What do I try last, before a new cartridge..." Thanks, Rick Glazier If you think your answer is too "off the wall", feel free to write off-list...
