Is this clean enough?
I assume that the answer is going to be "if I have to ask, the answer is no"
First pic is the before shot of this ETA 2369 mvmt that I picked up on ebay as a practice before I ruin a real watch.
Once I got the trian wheel bridge off I found that there was some corrosion on several of the train wheels, and a lot of the bridges were practically glued down with old oil and dirt.
Pic 2 is after 2 full cleaning cycles through my ultrasonic setup (still dirty).
Pic 3 is after manually scrubbing with pegwood.
My current cleaning procedure is:
- Naptha - Ultrasonic - 10 min
- 99% IPA - Ultrasonic - 5 min
- 99% IPA - Ultrasonic - 5 min
- 99% IPA - Ultrasonic - 2 min
This movement went through that procedure 2x and still had persistent dirt on these wheels and on the barrel bridge (I assume there is subborn dirt elsewhere too).
My questions are:
- is this clean enough? Or does this need to run through again?
- Should I modify my cleaning procedure/ solutions as it seems the naptha isnt cutting the grease well enough? L&R is out of my budget right now but trust me its very much something I plan to upgrade to eventually.
I've seen people say aqueous solutions can be good for grease.
I was wondering if a 2 stage wash could be good something like:
- Aqueous Wash - Ultrasonic - 10 min
- 99% IPA - Ultrasonic - 5 min
- Naptha - Ultrasonic - 10 min
- 99% IPA - Ultrasonic - 5 min
- 99% IPA - Ultrasonic - 5 min
- 99% IPA - Ultrasonic - 2 min
And if i was going to use an aqueous solution what would you reccomend? Ive seen this guy https://www.youtube.com/watch?v=z-SGm-nhGt8&list=PLvMdYdz6a-tElOsNLNR82Vy2RGAp1B1Ls&index=3 has a lot of good stuff for beginners and he says that a simple wash of distilled water and dawn
Any tips would be greatly appreciated!
