Silver Cleaning


Recommended Posts

Hello All;

When the servicing of a pocket watch with a cylindrical escapement came to an end, I was left with the question what about the silver case? The case had 0.800 stamps & silver-hallmarks all over the place, meaning that it consisted of an alloy with at least a 80% silver content.

With the movement removed, I tried one of those silver polishing hand-gloves. Indeed, I managed to clean the case up a bit, but to my horror I discovered polish-dust everywhere under every edge and in every seam ....... no good ! Cleaned to case thoroughly. A kind of silver-dip was required. Instead of buying (expensive) silver-dip, I searched for the internet for DIY and came across a method which worked very well for me.

The requirements are:

- Glass bowl

- 1x spoon (tea of table spoon, depending on the amount you mix) Baking Soda. (Warning !!; ask the wife's permission first !! )

- Some salt

- Aluminum foil

- Hot-water

The method goes as follows;

- Cover the bottom of the bowl with the aluminum foil

Add the Baking Soda, add some salt and add warm (tap) water, or better, if you want the do it the official "chemistry way", first the water, then the chemicals followed by stirring. Make sure that for a silver object with glass in it, the water isn't too hot. Also make sure that the object is made out of silver ! By Sliver-plated objects, or where the silver-plating is worn through, undesirable results may happen !!

Submerge the object in the fluid and let it rest on the bottom. Best is to check regularly to see if things go the desired way. It seems that if you leave the object in for too long, the silver color can become "dull".....

I first tried another silver object to see the working if this DIY brew, and it worked perfectly. The same odor arises as when using the "official" silver-dips. I used hot-water out of a water-kettle and by the time I was done with my dummy-run, the water had cooled down sufficiently to safely submerge the watch-case.

After I was happy with the results, I rinsed the case with tap water and to avoid any water stains, I rinsed to case in demineralized water and had it dried overnight on the radiator.

    • I was wondering whether anyone could assist with some questions I have about my latest acquisition, which is a two train ‘Bravingtons Renown’ mantel clock - Pics attached I have done some reading about Bravingtons and believe they sourced movements from various suppliers, so I wondered whether anyone recognises this one. I have stripped and cleaned the movement and the clock is now running well, but there are a couple of dodgy brass springs that I would like to replace. I haven’t found anything suitable searching the internet so I wondered does anyone know of a supplier that might help. Last question is about the veneer on the case, it is generally in reasonable condition but there are a couple of patches on the top where the veneer has lifted. So far, I have tried to reactivate the existing adhesive by heating from below and above with a hair drier, then clamping for a day or two. It has improved slightly but the bulge is still visible. I’d be grateful for any advice if anyone has dealt with this sort of repair before.
    • Hi some pictures o& the movement and case would be appreciated so we can ascertain what the problem is you are having in fitting the movement.   Thank you.
    • Thank you very much,T. I'll try turning the arbour from the clock face end very carefully in case I haven't reassembled the suspension block correctly (I had to make up a suspension spring using remnants of a broken one as I haven't been able to find an exact replacement online).
    • Hi murks a picture of the front as well would help,   By the size of the plate it was stuck to I would suggest a coin cell,  2030,  2015 all depends on the height of the cell. And the space when the back is fitted.         3 volt. 
    • We seem to have gone a bit quiet on this ?  Do we all agree to ask Mark for some input on this matter, or is no-one really bothered.
