I don't know what it is, can I see a picture? -
the ammonia product for cleaning your brushes you know what the chemical properties are or have a material safety sheets? As far as I know ammonia or I believe ammonium hydroxide but I'm not a chemist here I might be wrong as been used for watch and clock cleaning for a very very long time. The only experiences or knowledge I have a bit being bad is it will frost brass if left on long enough and frosting means dissolving the copper into the solution which turns are pretty blue-green color. Or on one professional discussion group somebody went on vacation with the watch in the solution and came back and needed an entire new watch and it was a very expensive watch. The claim was that only the jewels were left but I found that unlikely I suspect some of the metal was left but not in a functional state what I was cleaning watches at home and had a problem with the l&r rants not evaporating at all no matter how much heat and blowing from a hairdryer that I was using it just wasn't going to evaporate. A friend suggested alcohol. Going to the local hardware store I purchased a gallon of the same alcohol that's used to dissolve shellac it actually says that on the label. But the purpose of the final alcohol rinse is only to rinse off the prior rinses and I don't even think I was in their 15 seconds it didn't seem to be a problem at all we do end up with other interesting problems like shellac is not necessarily one substance it can be a whole bunch of substances. Then of course alcohol you need to specify which one it is. I did see on a woodworking discussion group the referenced isopropyl alcohol as to whether it dissolves shellac or not and? I think some people said it did but it took a really long time and we do end up with lots of variables so rinsing in the alcohol is fine just don't leave it in there very long just enough to rinse off the rim's and then you can dry as far as the cleaning goes I don't know how many times you can use it. I think somewhere I have documentation of what Swatch group recommends for cleaning but I don't think the using the water base and unfortunately Swatch group has infinitely deep pockets so their cleaning procedures will not match ours. Although I do know that other people that are using the solvent-based cleaners will use them until well they use him much longer than I would I've even known a people to filter them except that stupid because you Filter out oil that's dissolved in the solution. So I guess what shall have to do is just keep an eye on the cleaning fluid of it starts to look dirty or it's not cleaning then replace it I think if you look at the water-based cleaner it does have ammonia. But I think the key to cleaning with anything that makes things bright and shiny is minimalistic time is preferred versus something longer that will start to do bad things. Then typically anything other than the cleaner with the ammonia I don't know enough about the water-based but any of the solvent-based you can go much longer in the rinse because it's relatively harmless it's not dissolving or brightening things. Oh and they even do make a non-ammonia non-water-based cleaning product but in another discussion group somebody said it's still have a smelled too much of course all solvents are going to have some level of smell and it still contained chemicals to make things bright and shiny so I assume ammonia or not anything that makes things bright and shiny you basically have a time limit of bright and shiny and then it will start basically dissolving things like typically copper out of the brass. here's interesting video something dreadfully expensive. This is the cleaning machine that I use when I go to work. Let's look at all the things that we know for instance alcohol is bad but as per Elma's recommendation the last rinse is alcohol as the normal rents will not evaporate. Ultrasonic there's people out there that say that's bad this machine actually has two separate frequencies. Then just to make sure the fluid gets everywhere it even uses vacuum and yes the cleaning fluid really does go places that normally might have to disassemble. So we have alcohol to the frequencies of ultrasonic and vacuum that lets the fluid literally get every place and we clean all of our balance wheels pallet forks in this machine and cleans really beautifully is just a shame it costs such a huge sum of money. -

This is for an Elflgin 18s pocketwatch. This wheel came off arbor while repivoting. What is the best waybto attach? Triangular punch, pinch arbor, glue? This is my watch.
