A method and cleaning system to clean ink and coating from contact cleaner rolls. The contact cleaning rolls are located on a turret and as one contact cleaning roll is indexed sequentially out of contact with the imaging surface and into contact with a porous material another contact cleaning roll is indexed into contact with the imaging surface simultaneously. The porous material has a non-alcoholic solvent applied to clean the contact cleaning roll surface upon contact. The components found to create an efficient cleaning solvent for the CCRs include aliphatic ketones and alkylene halides. The aliphatic ketones are alkyl ketoses containing from about 1 to 25 carbon atoms (with a preferred range of about 1 to about 10 carbon atoms). The aliphatic ketoses contain solvents such as methyl ethyl ketone (i.e. the preferred solvent), methyl ketone, ethyl ketone, propyl ketone and butyl ketone. The alkylene halides are alkylene chlorides that contain about 1 to about 30 carbon atoms (with a preferred range of about 2 to about 12 carbons). The alkylene chlorides include methylene chloride, ethylene chloride and propylene chloride with methylene chloride being the preferred solvent.
