Yes, that was his comment. Also he was talking about polishing the plates.Hi times
Is that when he's talking about the brass tarnishing quickly? With the home made ammonia acetone oleic acid solutions this can be a problem.
It shouldn't happen near as much or at all with good commercial cleaners and good rinsing.
I think I'm using l&r 677 right now and #3 watch rinse in the waterless cleaning machine.
I dont think that was a mystery to anyone?Ammonia brightens brass, and the effect will eventually be reversed by oxidation. No mystery. Don't blame the cleaner
Nothing wrong with that, Frank, it looks great! I've never had the opportunity to work on a tower clock. I'm enviousRight now I'm cleaning four tower clock motion works that are absolutely filthy with 100 years of grime. I'm using Super Clean, a biodegradable, non ammonia cleaner, first in a bucket to get off the majority of the junk, then in my ultrasonic. It works great. Here is a comparison of before and after:
After I wire brush and paint the cast iron parts, I'll turn the rotating parts on my lathe to smooth and polish the bearing surfaces. Then the brass goes into DEOX - 007 for the final cleaning.
I still have yet to go the distribution plate that is as filthy. Brass bevel gears and a cast iron frame:
Not sure you be if you knew how many disposable gloves and rolls of paper towels I went through, and also how many times I had to scrub my hands. If I touched any part of them I couldn't touch anything else without changing gloves or washing my hands. I had to ultrasonic my tools afterward and clean the faucet handles. The sludge on the bottom of the pail and in the bottom of my ultrasonic was a quarter inch deep. Plus, I'm on a septic tank so the solutions couldn't go down the drain. Had to bottle them for later disposal.I'm envious
