Hot take: I thought ultrasonic cleaning brass gears was overkill until I saw the sludge come off a 1958 Leica
A guy named Ray at a repair meetup in Cleveland kept telling me to stop scrubbing gears with a toothbrush and Q-tips. I figured a brush was fine for 12 years of shutter work, so I ignored him. Then he dropped a grimy rangefinder gear in his ultrasonic tank for 6 minutes and the fluid turned into brown soup. I bought the same $120 unit the next week and it pulled 60 years of gunk out of a lens helical I had already cleaned twice. Now I'm wondering what else I've been doing the hard way, does anyone here still hand scrub on purpose?

Cleveland Ray was right but my 1950s Rolleiflex gears still get a hand scrub first.
