A customer's comment made me rethink my chain cleaning method

A regular at our shop in Boulder told me my ultrasonic cleaner was just moving gunk around, not removing it. He showed me his chain after using a simple Park Tool brush and degreaser, and it was way cleaner than mine. I switched to scrubbing each link by hand before the ultrasonic bath. Has anyone else found a better pre-clean step?

Moving gunk around" is a perfect way to describe my old method too. I mean, my ultrasonic cleaner was basically just a fancy soup maker. A quick scrub first saves so much time.

Used to think the ultrasonic did it all, but a good pre-scrub really does make a difference.
