Digital BW, The Print

Denatured ethanol (AKA: denatured alcohol) was / is the choice of printhead manufacturers / remanufacturers. When they recieve alleged "defective" heads due to clogging etc, they use this to "cleanse" the jets, typically by total immersion into an ultrasonic bath of denatured ethanol cut with purified water 40/60. (if memory serves). I have a pdf of a current MSDS sheet on denatured ethanol for anyone's review,  just request it off-line. 
Glad to help, - JT

 >>  My concern is the possible crossive effects of Windex (ammonia) on 
  >>  the print heads.  Any info on that?
