How about a basic ultrasonic jewelry cleaner with store bought jewelry cleaner solution?

Is it effective enough?

I really can't afford a professional cleaner at this time.

Sorry for the double posting.

Hi Geo, I didn't see your post about the new cleaning machine. How did it go?

 

 

@mlfloyd: The information is intermixed since we all use different systems of both professional and non-professional cleaning. Just do a search, there is plenty in here. I must add that if you use ultrasonic "jewelry" cleaners, you may get away removing the jewels from the cock and plate when cleaning the scape wheel since there is no cyclone action. Also, jewelry cleaner chemicals are not exactly healthy for watch parts considering some of them might have agents that might harm different materials used in those parts (example: shellac, etc). I would use those for bracelets, and such.

Hi Bob, if you are asking about the the old Brenray machine, I have been way too busy and lazy to look at it over the Christmas/New year period. Don't worry, I'll post a few lines when it's up and running.

Hi floyd,

 

jewelry cleaners are best for bracelets/bands but should be better than nothing.

 

Use smaller jars with cleaning solution and place it in the cleaners, (the ultrasonic transducer will usually be central)..I would imagine a thin plastic connector would transmit the ultrasonic waves better but I may be wrong.

Hi All

I'm a beginner.  I've run the balance jewels from an AS 1700 thru the ultrasonic.  The jewel didn't come out of the setting as it did the last and only time I've done this before.  Should it?  Otherwise, I can image that a bubble can form under the setting preventing any cleaning fluid from getting in.

 

Thank you

Charlie

Hi Charlie

Do you mean that the cap jewel didn't come off - are they Incabloc ?

Unless really stuck with old oil, they usually come off in the ultrasonic.

If not, try prodding them with some pegwood (under fluid so they don't ping off),  or press the cap jewel in to some Rodico.

Yes, Incabloc cap jewels.  Almost microscopic. 

Interestingly, it immediately came apart when I reran it with naptha instead of the cleaning solution that I mixed up from a recipe on this site.  That recipe is distilled water, murphy's soap, ammonia, and cascade.  Certainly safer to have in the house but now I'm wondering if it's optimal??  

Another question:  is it common for the top and bottom incabloc cap jewels to be different?  

The idea of prodding the jewel under fluid is very helpful and non-intuitive.  I've lost count of all my pinged off parts.  Maybe I should take this hobby into the pool:)

If they are different diameters then it will be clear which goes where. If there is a difference of thickness the thick one always goes on top- in the balance cock. Remember the sound a clock makes- tick tock: thick top. You won't forget!

Very helpful!  Are cap jewels symmetrically shaped or do they have an upside and downside.  Almost impossible to tell with the loupe.

I've just cleaned a couple myself - I use an old contact lens storage case to keep the jewels separate. 

A drop of lighter fluid, and float in hot water in the ultrasonic. Then rinse in isopropanol

Hello,

I have a question about cleaning. In the course I saw that if I don't have a cleaning machine I can clean parts by hand using benzine. 

I wondered if it could be a problem to put parts that have jewels fitted with shellac in benzine. As the benzine could melt the shellac. Is it ok to do it if doesn't stay to long in the solvent? How would you clean these parts if you don't have a dedicated watch cleaner?

Thank for your help!

For balance assemblies I find automotive brake cleaner, or electrical contact cleaner sprayed in a small bowl works very nicely.I tend to leave pallets alone unless they are dirty. I too am worried about the effects of solvents on the shellac, I have had stones fall out. If need be they get a dip in hot soapy water..for the shortest possible time.

I use naphtha and in my experience, the shellac will basically stay unaffected. However, I wouldn't leave those parts in naphtha for a week, but for a day or two I haven't had any problems, and I always check the integrity of the pallets and impulse pin after cleaning. However, be very careful with alcohol-based solvents such as isopropanol (aka IPA). I ordinarily rinse in IPA, but the pallets and the balance only for a few seconds and then I immediately blow them dry. The idea is to remove any remaining naphtha.

An ultrasonic cleaner and warm/hot water will do a decent job (I use 60 ml glass jars with naphtha that I place the parts in and then the jars go in the ultrasonic cleaner). However, the ultrasonic cleaner will not be able to remove rust, corrosion, and some other stubborn dirt, so after cleaning I always inspect the parts and use fibreglass scratch brushes (my no.1 favourite cleaning tool)  as needed and rinse in IPA again.

Good luck!

For you guys doing hand cleaning with naphtha or any solvent it's important to dry in warm air, a hair dryer is fine. The evaporation drops the temperature and there's a real risk of condensation and rust on the newly cleaned steel. This is why the old books are always talking about drying in warm sawdust.

Oh, forgot to mention!

Big parts (main plate, bridges, and even some medium sized parts such as the ratchet wheel, etc.) I clean using warm/hot water, detergent (Yes!), and variously sized toothbrushes! It's super efficient and after this treatment, the parts look all shiny and new! Haven't found anything that beats it, and I even doubt a watch cleaning machine would do a better job. However, be careful to blow everything perfectly dry as soon as possible to avoid the possibility of any rust building up. And, I never use this method for the train wheels as they rust very easily.

you can get yourself a jar of one dip for pallet and balance, 2oz bottle will cost you $9. and a bottle of ronsonol lighter fluid for the rest. or use the lighter fluid for everything. you can manually clean after a soak with pegwood, rodico, and fiber brushes. some guys make their own water based concoctions but was never really a fan of water based cleaners, i prefer solvents. they work better at removing old oil if you are not using an ultrasonic.

Mineral spirits on everything but hairspring and pallet..let the parts soak.All the crud gets dissolved or falls off.you might want to change it once or twice on a really filthy movement.I put the parts in a small dish inside a biscuit tin so it doesn't evaporate.

Thank you all for all your tips.

This forum is pleasingly active. You guys helped me get years of experience in just 24hrs!

I can see that like in every trade, everybody experiments and sticks to what work for a specific person, his liking and environment. Thank to your help I'll have the opportunity to make my own experiments.

I already tried to put a flake of shellac in benzine for 3 hours. It came out unchanged. I don't have to do the experiment in IPA or ethanol. I know the answer. These are the solvents that I use when I prepare my wood finishes. (@nickelsilver : thank you for pointing it out. I didn't suspect that)

Please allow me a few more questions :

Is there a risk that the glass fiber brushes leave marks on the metal parts? How to you use them? Liberally or with specific care?

For those who use One Dip, how do you use it? Do you transfer it to a more practical jar to use it and then back to original container?

Glass fiber brushes won't really mark steel, and are effective for removing rust spots. They will mark non steel parts. I only use them on steel and as seldom as possible as the little broken fibers get EVERYWHERE.

    • The watch is from 1990 and was serviced just once around 20 years ago. No idea if the mainspring barrel was ever opened or changed before now.
    • Interesting but I think we have a problem here? We probably need to split hairs on a definition problem. For instance take a real Rolex movement put it in a real Rolex case but not the one it came in take a real dial real hands and make up a watch that is 100% real and what exactly is this? If you send your Rolex in for servicing and anything's been changed at all from what it was when it left the factory Rolex will be unhappy and remove all offending components. This does become a problem of people changing things because they think it's their watch and they want to have a different dial Lord diamonds the bezel or whatever words Rolex sees all of this as evil and bad as far as a Intel Rolex only things the watch is legit if everything is exactly what it was when it left the factory and nothing's been changed including the stem everything asked me Rolex original or their very unhappy about its existence. Then you think about a fake watch what is its real purpose? Well its real purpose is to make money for somebody and fool the customer. So all the watch has to do is look pleasant on the outside and inside can be anything. Typically nobody's going to see inside. So typically anything that's not legit counterfeit movement etc. why would someone spend so much time and effort making it look just like a real Rolex when there's no need to? Unless of course you have one or two movements to impress somebody with this is what's inside your watch but even that is problematic Now we don't end up with I've interesting problem that troubles me where I work. The owner will offend a cage your watch by looking at it carefully with a microscope the timing machine etc. and he will point out all the things that he feels are not appropriate correct or whatever for your watch. But in my example above of mixing and matching legitimate Rolex parts he wouldn't necessarily be able to tell. The problem I have with this is it often times things like his claim to telling a counterfeit is look at the second hand the quality of the secondhand is not as nice as a legitimate one. But maybe somebody replaced a second hand on a real Rolex. Or the other day at work I don't know what it was in before but there was a really pretty movement transparent back and they decided it was fake because of? Now I didn't think it was fake I took one look was beautifully manufactured but they had a reason What bothers me with counterfeit Rolex is or anything counterfeit watch related it is reminding me of a witchhunt. The early days of witch hunting how can we tell a which Manon which? That makes me wonder how many super fakes are really fake at all it's basically somebody deciding it's a fake based upon inappropriate assumptions. Like the secondhand is been changed or the watch was worked on the screws are perfect or other things. Other minor problems with super fakes for instance I have a long story the not going to tell the short version is I found the website once where they claim to be counterfeiting Rolex watches. They even had a picture to prove their counterfeit watch the problem with pictures online how do we know it's really a counterfeit watch and not a real Rolex watch that you're telling us is counterfeit. Oh and they had testimonials from all kinds of people who bought their watches and were very happy with the service of course the problem with the watch is you don't know what's inside it unless you take the back off and just because somebody shows a picture online and says this is their super fake maybe it really isn't a super fake they be there just trying to say that. We end up with a interesting problem of manufacturing a watch. Does Rolex actually make every single part found in their watch? Then the year 2004's basically irrelevant. This is because initially Rolex buys stock in the company and they manufacture Rolex watches. I'm assuming over time Rolex will acquire more stock and only in 2004 do they get the whole company. But the company itself hasn't really changed other than the name on the front of the building. The real question is did they really make every single component found in the Rolex watch from the beginning of time until end of the time? A lot of the components found in a watch would be extremely specialized did they make their own jewels or their own mainsprings for instance? But that is looking at the article they employ a heck of a lot of people now I would guess now that Rolex probably does make everything in-house. Especially when they have nifty CNC equipment like for making screws were he could make a huge batch of one type it instantly switch to another type where before he needed specialized machines for one machine for one screw now manufacturing all kinds of stuff in-house becomes very simple. But still is possible that in the early days they might have outsourced something may be perhaps. But conceivably we do have minor changes in thing is due to how things have been made over time which can lead to confusions over whether this is legit or not when it may be as a change of manufacturing methods oh and regarding the screws found in your Rolex watch? In about mid-80s I went to a school reunion in Switzerland. One of things we could do was visit a factory and I picked Rolex because I wanted to see the mass production making of Rolex watches. Which is very disappointed I did not get the sea at all because didn't see them making Rolex watches in their Geneva headquarters even though the building is really fake? So what did we get to see well after sales service because after all were watchmakers we should see that. Did learn something interesting about Rolex screws if your watch was sent to Rolex the screws that come back are not the ones that went there. As they are using powered screwdrivers they don't want to risk breaking heads off and they will replace the screws of every single watch. The other one of interest was suppose there's a scratch and you can see the brass? No problem they have a solution that basically electoral plates without electricity so the scratch goes away. The research Department was quite boring and didn't look like anyone was ever there. Then it was too long ago to remember all the details other than I was disappointed I want to see manufacturing.   Yes the joys of artificial intelligence that is more like a trained monkey that's there to please you.
    • Hey everybody! I just registered to WRT. I found this forum searching for informations about ELMA watch cleaning machines (will get one ELMA tomorrow ✌️). I'm new in watch repair, collecting watch repair tools to fill up my work space 😎.   Greetings from Vienna Michael
