buttermilk - can it clean silver?

Postby Hose_dk » Sat Sep 14, 2013 1:30 pm

The test is carried out as I write. So I dont know the answer. I bought a fantastic bowl today. Very butiful and fine hand made. Is it silver? I dont know, but I hope. As fantastic as it is. Its also so dirty. The green colour normally tell - copper. But in this case it could be green from the imtem held inside by the owner before me. We start by showint the bowl. Thailand?

Image Image
Inside very green - and lots of "patina"
This is our starting point. Lets add some buttermilk.
Image
And wait a few hours.
Image Image
Another half hour in the buttermils and a brush to get Down in the pattern.
Image Image
And details
Image Image
Butiful details, but it could very well be that I have to continue all night, there is still much to go.

I left in outside in the garden and it has rained. So buttermilk has had Water added. Not for the better.
Image Image
This morning I gave it a tour with a toothbrush. Inside it has some effect - but inside is also a lot of surface. Even surface.
Image Image
Also on the outside i has been cleaned. But Again mostly on the top. Where the brush and my fingers has most effect.
Image
Dont know - I think that its the mechanical that Works. We see this afternoon.
But a lot of dirt was also removed this morning. It made the buttermilk darker.
The one WHO told me of this method explained that I would get a colour that had a ..... (dont know Word) but not as shiny as polish. Could he have been taling of the Black & White efffect?

Project buttermilk terminated and projekt burger started

11 oclock Remulade - mayonnaise - tomat pure - mustard - ketchup going from 11 oclock going right.
No effect what so ever of more than 1 hour of test.

Project polish next try. Any good idea before I start that one?

I decided to polish. An ordinary silver polish followed by an hour and a half in buttermilk. Then cleaning with a dishwasher soap, and a tooth brush. Followed by tooth pasta and a wash in warm Water.
Could be that I should stop?

It just goes to show that there are no shortcuts. I think I'll stick to silver polish on my silver and food in my mouth.

We are still in the mombo jombo business. Test the use of hot Water, salt (natriumklorid) and aluminium folio. The natriumklorid should have been natriumkarbonat but I did not have any of that.

Water has been added and we see the bobbles comming. We wait and see result :-)

Hmmmm a lot of dirt removed. However not all. Mechanical still Works best for me. I know that its me - the method should Work. But for me ??
Image Image
Before the cleaning today & After today cleaning.

Conclusion for me - I can see that it Works a lot less of the red dirt.

I have used this process in demonstrations but I used potassium bitartrate (cream of tartar). It takes a while with heavily oxidized pieces, can remove more oxidation than I typically prefer, and leaves a piece still needing polishing to bring up the luster.

Hose_dk. Have you ever tried Sodium Carbonate or Bicarbonate with the hot water and aluminum foil method?(I have never tried salt) Been told that it only removes the silver oxide (tarnish). I have used it on silver items found while metal detecting and it seemed to shine them up decently.
