Serious question, did anyone else think ultrasonic cleaners were overkill until they saw one work?
I used to scrub leaf shutters by hand with a toothbrush and lighter fluid until a guy at the Ohio camera show in Columbus dropped a filthy Compur from a 1952 Rolleiflex into his ultrasonic bath for 4 minutes and it came out looking factory fresh, so now I want to know what temp and solution you all run because I'm about to buy one.
