What is the most time I should leave brass plates and wheels in cleaner when using “soup”?

Hello John,
I usually run it around 10 minutes or so. I often
do a bit of hand cleaning first with a brush and
Coleman lantern fluid and always fully disassemble
the movement. You can let it run longer if needed
but have to be sure the movement isn’t lacquered because
the U.S. will remove the lacquer! That occurs somewhere
around 15 minutes in my machine. I use ammonia based cleaner.

Best, Dan

Thanks for your advice Dan, appreciate it.

Regards,

John.

This might be a stupid question, but, how would one tell if it’s laqured?
