Ultrasonic cleaning questions "Click" to Login or Register

Hello everyone! I’m a new hobbyist clock cleaner working on my in-laws’ grandfather and two mainspring clocks. After much trial and error, I fully disassembled the grandfather clock movement and carefully cleaned out all the gunk. I then used some Formula 67 and two subsequent rinses of Drizebrite, but I just used these solutions in Rubbermaid containers and found the process very difficult and messy.

I want to consider an easier and more efficient style of cleaning and was looking at ultrasonic cleaners, specifically the Co-Z 2L cleaner. However I’m concerned because I read that using my flammable ammonia-based solutions in an ultrasonic cleaner poses a severe fire hazard, and I am just doing this process in my basement.

What are your thoughts? Is it safe? Do I need to only clean the parts without heat to minimize vapor generation? Are there other options for clock cleaning machines? Thanks so much.

Heat will destroy the solation. The movement will clean in cold solation.
