The ultrasonic cleaner arrived today. I should’ve taken a “before” picture of my Mark II; the breech face was all crudded up with a mix of lead and powder to where it wasn’t reliably extracting, regardless of what ammo I gave it. After 15 minutes in the cleaner with some Ed’s Red I mixed up, it’s clean enough you could eat off it…if it weren’t so small. :) The Blackhawk’s in the bath now. Only prep for both was to field strip and remove the grip panels.
