Tom, I’ve got two retired clock guys here that told me to mix 1qt. naptha with a gal. mineral spirits as a rinse, after cleaning with a non ammonia cleaner. You don’t use naptha in your ultra sound do you? Mahlon

Mahlon:

I don’t use an ultrasonic machine. I use a manual seven dip process lised in the Chicago Watchmakers Course – only because I haven’t bought one yet. However, David seems to have had good luck with that and hasn’t had any fires yet.

Thanks!
Tom
