Was skeptical about ultrasonic cleaning for shutters, now I swear by it

I thought it was just hype for years, but after I wrecked a shutter curtain on a Pentax 67 with isopropyl alcohol alone I finally bought a $200 ultrasonic from Amazon. Three minutes in the bath with the right solution and that shutter was spotless, no damage at all. Anybody else had good results with ultrasonic on older leaf shutters?

Did you seriously wreck a shutter too before trying the ultrasonic?
