Dear Scott, IPC 600 5.0 is a cleanliness test section with the references to 650 test methods. Not sure that's really what you need. We clean with a scrubber fitted with a nylon brush, filtered pressure spray rinse, and hot air blow dry. We rack vertical in front of a fan before stacking. Good Luck!
