Take out the mechanism, amplifier, power supply and any of the easely removeable items and vac out the cabinet.
Using warm soapy water wash down the interior, rince and dry down fully.
Strip down the mechanism to clean it, again I prefer just soapy water, inspect all the parts for wear and replace where needed, rebuild and check all adjustments as per the manual.
Only lubricate as indicated in the manual and only sparingly, for example the gripper bow assembly has high melting point grease in the two trunnion sockets only, no other lubrication is required.
