Clean as a Whistle

Deep clean

Joseph Ialacci, president of Magnum Research Corp.: “One of our regular flexographic printing carton customers who regularly ordered our Flexo Kleen Plus anilox roll cleaner recently asked what we recommended for periodic deep cleaning. Flexo Kleen was working for [the carton converter] as a regular cleaner, but felt [it] needed to use an ­aggressive but safe, once-a-week-type cleaner to remove and clean the extremely stubborn ink dried in the cells. [It] thought of using a more caustic cleaner to get rid of stubborn embedded dry ink that wouldn’t wash off, but the high pH could have damaged the cells. Other methods such as ultrasonic baths and media blasts required them to take the rolls off the presses for cleaning, sacrificing printing time they couldn’t afford to lose.
