Elma red is a very good cleaner and makes parts shine, but if there is any hint of tarnish of the nickel plated main plate or bridges it can clean the tarnished sections right down to the bronze layer, in as little as 5 min in Ultrasound... the untarnished parts will really sparkle though.

According to H S Walsh  It can be used in watch cleaning machines or in ultrasonic cleaning baths. no mention of using it for cleaning parts by hand. If it is that aggressive I can't think why one would want to use such stuff.

Not too sure why but the tarnished parts of the movement mainplate/bridge on a movement I was working on came off entirely and I could see the bronze when I ultrasonicated the parts in diluted Elma red (1:9) as recommended. Could be that the nickel plating on the tarnished parts was very weakened.

It also caused the parts of my bronze tweezers it contacted with to shine. I used it as a dip for the the train wheels, to make them shine!

As the origional question was cost related, two cheap and readily available probdcts in the UK are carburetter cleaner and automotive brake/clutch cleaner both contain Naptha , a petroleum distilate and Isopropyl alchohol plus butane as they are pressure cans. Again I have used both with no problems in either drying or cleaning/degreasing. Usually used in small jars in the U/s. On the question of Ultrasonics If they are not recommended, why have companies such as Griener, ELMA, L&R. Watchmaster to name but a few ,invested money in creating machines that are ultrasonic, and dual machines with both U/s and conventional operations. It seems that its wide open to debate as far as preferences go.  I think is a personal choice.

I think the ultrasonics in the professional watch cleaning machines are fine, as they rotate the parts to prevent continuous cavitation in one part. The cheap ultrasonics used for jewelry is also fine most of the time, but @HectorLooi and @Nucejoe have warned about their use potentially causing damage under some conditions. I use a cheap ultrasonic myself to clean some parts of a movement with diluted Elma red, but I have observed plating removal if the plating has been damaged prior by old age/tarnish.

In addition to those two naphtha containing products  @watchweasol recommended, I would also recommend some peg wood for cleaning. You may be able to use high quality wooden toothpicks instead though... In any event, after cleaning the movement, you would still have to oil it when you put it back together, so I’m not sure how low cost it will be once you add the prices of all the other things you would have to purchase.

Heres the instructions on the back of my Elma Red.

Thanks for all of this and for the suggestion over-and-above cleaning fluids regarding pegwood. I am set on the oiling as being unavoidable and am going to space out buying those so that I'll do the oiling maybe at the start of November. I'm not in a rush!

As with all cleaning agents we all have our preferences and methods. The main precaution being,  read the instructions on the product or better still get the safety sheet  and exercise common sense in the use of these chemical as some are highly in flammable or even explosive in an enclosed space.  The watch word is CAUTION.

Since you’re in the UK, you can get watch supplies for low delivery fee from cousinsuk. For your maximum enjoyment, I would recommend at the bare minimum one bergeon or dumont brass tweezers, screwdrivers (you probably already have this, since you took a movement apart), movement holder, a loupe (optics), a set of oilers, some pegwood, a rubber bellows, and your choice of oil, and choice of cleaning fluid.

The safety aspect of the cleaning fluids cannot be stressed enough, since whatever you use will be either flammable, toxic, or both. Ventilation is the most important when using these. Be very careful if you are doing using them during UK winter, Since your windows are likely to be closed.

I got isopropinoal from a pharmacist, he wrote very toxic on the bottle before handing it over, should not be drank, get in eyes etc, I think I inhaled some so been dreaming naked old girls in sleep.🤠

Let's put things in perspective, these label warnings at our age should be well know already.
Amount of of petrol/alcohol/whatever else is needed for manual cleaning, 20cc in a jam container with lid. Exposition time while pouring, replacing etc. 20 seconds.
Tanks heaven out is a very low risk hobby/profession.

I find that the greatest exposure to naphtha is when I dry the part with my rubber bellows after taking it out of the liquid. Always will have a fan blowing at me to disperse the vapors.

Thanks - as a Science teacher I appreciate the common sense of giving this advice, but no worries. Unless I'm a complacent Science teacher. Then I guess I've got issues. Thank you!

As you  are a science teacher we were teaching Granny to suck eggs.  I had a science teacher in the 50s put himself in hospital twice sniffing gasses that had been produced with the bee hive jar under water. He was just a bit eccentric but a nice chap for all that.   I have on my system several informative documents if you are interested PM me as they are PDFs and un supported on the site.

Indeed.  Whenever the topic of insecticides, pesticides, herbicides, radium, falling airplane parts, spontaneous combustion...etc. come up in conversation, I routinely point (anecdotally) to my Dad who died at 93.  He was deployed overseas during WWII (no warning labels on anything), worked in the oil field, routinely sprayed chlordane on the yard whenever some bug irritated him, sprayed his vegetable garden with whatever killer spray he had on hand and worked on watches with radium for several decades.

I am not like my Dad--am far more circumspect about things that can damage or kill, but I still have volatile chemicals in my lab/watchroom.  Sometimes I even use a pair of these WITHOUT wearing safety glasses--realizing all the time that I am throwing caution to the wind!!

Warning labels are everywhere but I think your cutters are specific for the USA market. Especially in the country where someone has been awarded millions for having got scalded with hot coffee, companies place and push for these things in the hope to reduce liabilities.

Actually, if you are a science teacher you may be able to get your colleagues to give you a small amount of scientific grade petroleum ether (naphtha, in other words) for you to clean the movements.... Just be sure to make sure it’s not diethyl ether (which will evaporate too fast) or actual benzENE (which can give you liver cancer).

I'm of the (ahem) older generation.  My father's famous words if I was going to do something I hadn't done before - "Min' an' use yer heid" - meaning remember and use commonsense.

Perhaps my pet hate is the warning you sometimes get over hot taps - "Hot Water.  Danger of scalding!"  Well, no sh** Sherlock! 🙄

I have have never heard of any watchmaker, professional or not, which recommend soaped water. It's just not right for cleaning a watch mov.t.

 

 

You completely missed the point of my post 😉

The O/P was asking about a low cost solution. And believe it or not water and dish soap does a very good job of removing oils and grease, it's what dish soap was designed to do.

It not be used by any watch maker professional or not that you know of, that does not make it any less good at removing oils and grease, I bet the average frying pan is far dirtier than your average watch.

I agree it my not be the best and it may not generally be used by watch makers, but that does not make it any less effective at doing what it was designed to do and at a low cost which was the point of the O/P

I will step away now.

Dish soap is very good at cleaning my dirty greasy dishes. Certainly not for cleaning watch parts. If I was still working as a watchmaker I would be using L & R watch cleaner & rinse & Ronsonol for the balance and pallets.  

Posted

I have tried a few but always go back to the L&R. The bottom line how clean is clean. The vid I posted is in my opinion is a cheap option and IMO is perfect for those who are just cleaning a couple of watches a week. When I first purchased  the Pearl I was sceptical but under my microscope I could not fault the cleanliness. Considering how much I spent on the L&R Varimatic there is no difference in the final results. For those who don’t mind cleaning and drying by hand water is an absolute no no. A liquid I use a lot for de-greasing is mentholated spirit. It’s a bit smelly but shift grease and is really good to use before glueing but it’s cheap.

If one looks at the old ingrediants used by some of the old watchmakers for their own brew cleaners there is usually the inclusion of soap.

Some still use this in preference to the shop cleaners,  can't vouch for its effectivness but some swear by it. in all cases they recommend a final rinse in alcohol.

Dist water        2 to 3 Litre

Oleic/oxalic acid      3 tea spoons

Ammonia      1.5 dL

Alcohol      4 to 5 dL

Dish soap     2dL

I have a recipe that was published by Gruen, I think it was during the war for "getting things done". It's not that different from the Finnish recipe I use for clocks.

Gruen recipe:

1 ounce oleic acid

2 ounces acetone

4 ounces 22% ammonia

25 ounces distilled water

 

The oleic acid and ammonia combine to form a soap*. Oleic and oxalic are quite different; oleic is essentially pure fat and liquid, where oxalic is from my experience crystalline, that is perhaps why the addition of some soap in the above recipe. Rinse in distilled water 2x and finish in isopropyl alcohol, dry in warm air.

 

*The most traditional soap is some kind of fat mixed with sodium hydroxide, or lye, a very strong base. Ammonia is less basic than lye, but works great and also has its own cleaning action.

I sometimes us small amounts of dish soap as a surfactant when I'm cleaning things (not watch parts) in the ultrasonic.  Water, ammonia, and dish soap seems to work pretty well, saves buying jewelry cleaner solution. I'll have to try adding some acetone next time.

    • If he was much younger and some sort of sports player it wouldn't be a problem. They would be in there and doing surgery and he'd be back on the field in no time. Unfortunately when you get older little things are bad and big things can be really bad so not good at all.
    • Where I work everything incoming watches whatever detailed descriptions are taken entered into a computer program and photograph of each item. Then ideally although it depends on who's doing the paperwork detailed descriptions can be quite good other times there lacking. Like I really like it with pocket watches if they would record the serial number it avoids confusion later on. Then when watch repairs are completed that is also entered in. It's one of the amusements I learned when I was in school instructor had a shop and commented about the important aspect of keeping detailed records of repairs. Because oftentimes a customer who got a new crystal will come back later on when the watch doesn't work and expect you to fix the entire watch for free. Then you can remind them that they just got a crystal. Strangely enough that keeps coming up or occasionally comes up where I work now. One of the problems of using the service marks on the case is that in the case of pocket watches oftentimes that's not the original case. Then case marks? What I was doing warranty work for a company I used to describe a code number in the back of the case and it would tell me the next time I see the watch that basically what I did I made no attempt at keeping track of customers because we had literally thousands of them I think they sold 30,000 of these watches and they would come back by the hundreds because they had a lifetime warranty. Yes that's a story all of itself but I would put a code number that would reference what was done to the watch the last time and think I had a date in there somehow so it did tell a story if you knew the code. Another shop I once worked out the number would reference the page in the book. So other than knowing we had been in there you would have no idea what happened because you have to go look at the page in the book to see what happened. Then the problem of how you examine a watch you should examine the watch in detail every single time to avoid complications. Although on vintage watches and this is a of amusement I have at work when people ask something and I say of the watches done when it leaves. This is because on vintage oftentimes problems won't show up until the watches much farther into the repair like it's now running and you discover things that you can't discover before because it wasn't running to discover them that also become sometimes difficult to have exact rigid prices are estimates of repairs or in the case of a pocket watch you may not find out if a casing problem to later on when you case it up in the watches running. I was just thinking for all those people that would like to leave a mark maybe you should learn to do what some of the past watchmakers did? Leave a mark but leave it in such a way that no one will ever find it? Typically not done for repair purposes but done for other reasons like identifying it's legit. I have a friend with a Gruen watch and one of the Roman numbers the bottom line that just looks like a line under extreme magnification actually says Gruen watch company or something equivalent. So here's a link showing how to mark your watch without being seen although that's not the actual title. So if you can learn micro engraving you can engrave the watch someplace probably just about any place you just have to remember where you put it. https://cnaluxury.channelnewsasia.com/obsessions/how-to-prove-if-watches-are-authentic-secret-signatures-182516  
    • I have acquired a Citizen Leopard 36000 watch. My reason for purchasing it was my desire to own a timepiece with a 36,000 BPH movement, and the price was reasonable. Another motivating factor was gaining hands-on experience with the mechanism. The watch is in good condition, but I intend to fully disassemble it for maintenance. First and foremost, if anyone has prior experience with this particular model, I would greatly appreciate their insights. I do not have access to Citizen’s specialized lubricants and will need to use the ones available to me, such as 9010, 8000, and 8300 grease. Additionally, I do not possess the appropriate oil for the pallet jewels and will only be able to clean them.
    • Hello all, I am working on an older Valjoux Chrono. It doesn't have a stamp on the movement anywhere but I believe it is a Valjoux 72. I installed the train of wheels and they will not turn. The problem appears to be the 4th wheel and the escape wheel are not interfacing correctly. I had to replace both of these parts as the pivots were broken on each. I sourced genuine Valjoux/ETA replacements. I think the problem is with the escape wheel as all the wheels turn perfectly if I remove just the escape wheel.  My question to those with more Valjoux experience is am I mistaken? Is this some other model altogether and I have the wrong part or parts?    
    • I would remove the wheels, check for damage and if not damaged, clean.
