My cleaning methods depend on what I'm cleaning, but a general rule of thumb follows this process ;
1 - Separate parts into bins - metal, plastic, PCBs, wire looms and parts that cannot be put in the cleaner.
2 - Run them through the Ultrasonic Cleaner
3 - Run Metal parts through the Tumbler (course)
4 - Run Metal parts through the Tumbler (fine)
5 - Clean Plastic parts with Novus etc
6 - Place cleaned parts in parts bins for that machine
7 - Identify parts that need replacement or repair
Here is the playfield wiring loom placed in the Ultrasonic Cleaner's tray.
