A contact cleaning system, comprising:

• a conveyor, the conveyor comprising:
• an inbound conveyor;
• and
• an outbound conveyor spaced apart from the inbound conveyor by a distance;
• wherein the inbound conveyor and/or the outbound conveyor is movable relative to the other of the inbound conveyor or the outbound conveyor between a retracted position in which the distance is a first distance and an extended position in which the distance is less than the first distance;
• and,
• wherein the conveyor is configured to support a substrate on a conveyor surface;
• and
• at least one of:
• one or more upper contact cleaning roller positioned above the conveyor surface, wherein the one or more upper contact cleaning roller are movable between a cleaning position in which a surface of the one or more upper contact cleaning roller are arranged to contact an upper surface of a substrate conveyed from the inbound conveyor to the outbound conveyor, and a withdrawn position in which the surface of the one or more upper contact cleaning roller is withdrawn upwards, away from the inbound and outbound conveyors, or
• one or more lower contact cleaning rollers positioned below the conveyor surface, wherein the one or more lower contact cleaning rollers are movable between a cleaning position in which a surface of the one or more lower contact cleaning rollers is coplanar with the inbound conveyor and the outbound conveyor, and a withdrawn position in which the surface of the one or more lower contact cleaning rollers is withdrawn below a plane of the inbound and outbound conveyors;
• and
• wherein the inbound conveyor is arranged to convey the substrate towards the one or more upper contact cleaning roller and/or the one or more lower contact cleaning rollers.
