The spin clean works quite well. Not sure if you remember my ultrasonic post but I did some microscope magnification of various cleaners, one of them with SC.
My latest setup is 30 min in the US cleaner, which is distilled water, 99% IPA and Trition x-100 @ 30c. Then I take them to the spin clean with a distilled water 90%IPA for a few turns in both directions then hung to air dry
