Guys,
When I had my first complete movement for cleaning about 6 weeks ago, (as a total Newbie), I used a commercial ammoniated concentrate. This was diluted 7 to 1 as instructed.
However, I did not have the most suitable of containers for the job. I ended up dipping the movement one way up and then the other, because it would not fully submerge in the too shallow container. I washed and finally used a hair dryer.
The net result was a serious staining on the brass front and back plates. (See first two pictures)
Today, having bought an Ultrasonic bath, I used the same type and concentration of fluid but at 25 C and ran several cycles in the unit. Whilst the plates are better, they are certainly not without stains. (See pictures 3 to 6)
Chains and wheels done in the same session seemed to be pretty bright and clean. I did wash all the parts , as before, but now also rinsed in Isopropanol and then forced dry with a hair dryer.
Can someone please advise? Obviously, I messed up badly on my very first attempt. However, are these stains now more or less permanent or is there a simple procedure to remove them? Why did the Sonic bath not do a better job?
Best regards, Howard
