I cleaned and repaired clocks for many years.  I had no trouble with 
ammoniated solvent cleaners, with ultrasonic machines.  A few movements
had patches that remained dull after cleaning.  These were mainly the German
made ones.  The problem seemed to be that the plates had a gold " Flash " 
over the brass.  This plated layer was missing, or came off during 
cleaning, in patches on some clocks.  The solution was to buff the movement 
plates with brown tripoli, and re clean.  It is important to use a good pure 
cleaning solvent, that leaves no residue, as an ultrasonic rinse.  
Ordinary paint thinner is no good.  Two seperate rinse baths is the standard.
Then dry with forced hot air.
