I finally bought a Lyman ultrasonic cleaner, primarily for cleaning parts, my .22 suppressor, the "new" pistol that apparently wasn't cleaned since it was made in 1922, and so on.
I've seen the various solutions people use for cleaning brass, but I haven't seen one for cleaning metal parts. (I don't think the water plus a few drops of detergent plus some lemon juice is the best bet for cleaning parts.)
Does anyone have a pet concoction?
Thank you,
Richard
